VAZ 2107 stalls and does not start. Why does the engine stall? Causes of engine stop and solutions

This article will tell about why the car stalls on the go. The reason for this phenomenon may be the most banal, but trouble from such a "behavior of the car you will get a lot. In addition, the engine can stumble at idle. A little pleasant in it, the motor seems to be started, but after a while stops working. This option is possible, in which the engine does not want to start if its temperature is approximate to the working. Engine operating temperature is about 90 degrees. And the reasons may be much, but you need to consider the main.

The most common cause

It is worth paying attention to the fact that all reasons can be divided into several categories. Why does the car stall on the go? The reason can be both banal and complex. If we are talking about injection engines, the regulator is very often fails for turnover it supplies the required amount of air to the fuel ramp. The idling regulator is a stepping electric motor, it takes off and closing the channel, which passes clean air into the ramp for mixing. So, the first thing you need to make sure in the health of the idle regulator. To do this, scroll the crankshaft with the starter, simultaneously squeeze the gas pedal. The motor is started, but the number of revolutions is constantly changing. There is a breakdown of RXX - the engine stalls when pressed for gas. And the most effective way to get rid of such trouble is the complete replacement of the element. You need to install a new VAZ car it is done literally in minutes.

Throttle problems

Quite often the reason that the engine begins to stroke, the throttle itself is itself. It is possible that the air filter was worn out, so inside the entire surface of the flap was contaminated. To fix this breakdown, it is enough to clean completely from the inside the damper. Please note that after careful cleaning, the problem may be preserved, the engine still stalls when the gas is pressed. In this case, it is necessary to make sure that the position sensor is in good condition. This sensor is a variable resistor. It is installed on the valve axis. Moreover, the maximum wear is observed in the extreme position (corresponding to idle speed). If it fails, then it is necessary to completely replace it. The cost of the part is quite low, and the replacement occurs literally in minutes. But it is possible that the engine begins to stamp, despite the fact that all sensors are in perfect condition.

Fuel quality

Always follow what gasoline you fill your car. In most cases, all the above symptoms are manifested then as soon as you refuel the fuel tank. Of course, the motor can stumble and after a while. Therefore, it turns out to be difficult to determine immediately breakdown. It is also worth paying attention to: the reason for the fact that the engine begins to trim, should be shattered, it is always always in the gasoline itself. To cure such a "disease", you will need to completely drain gasoline from the tank, and also replace the fuel filter. Unfortunately, at refueling, you do not always buy high-quality fuel. Therefore, it is worth choosing one brand of the manufacturer who sells the highest quality gasoline. Of course, there are cases when the car stalls on the go (the reason for this lies not in gasoline). Please note that excessively low cost is the first sign that gasoline has a dubious origin. And pour it into the tank - it is equivalent to the fact that send the car to complete the move in the pillar.

Spark plug

To make sure you need to unscrew them all, check the size of the gap, as well as the presence of a car. And you have a car stalls on the go. The reason may hide in candles. In the event that there is a strong Nagar, but the clearance is within the limits of permissible values, it is necessary to clean the electrodes of the candles. But the best way out is to establish new candles. In the same case, if the clearance is very large, there is excessive wear of the electrode, cleaning will not help, it is necessary to completely replace the set of candles.

Fuel filter

But another very common reason at which the car stalls on the go. VAZ or foreign car - does not matter. But it is especially important for old cars. Some drivers simply forget that the car has a filter for gasoline cleaning. It is located at the bottom of the fuel pump. Of course, in the presence of dirt in the filter, gasoline enter the fuel ramp and the combustion chamber will simply not be. Must appear interruptions in the supply of fuel. At the same time, you, clicking on the gas pedal, shuffle the engine. To get rid of this malfunction, it is necessary to remove the gasoline pump, replace the filter. It is also worth considering that the tank itself can cause fast clogging of the filter. Therefore, it will be able to help or replacing the container or careful cleaning.

Air filter

A similar situation, as in the case of a gasoline filtering element. Please note that the operation and repair of the car must be performed in accordance with the requirements of the manufacturer. After all, you know that a mixture of gasoline and air is served in the combustion chamber. Therefore, if some component of this mixture will not flow into the fuel ramp, the engine will be stuck. Consider an example of how the motor works with a lack of air. The combustion chamber falls too much as the candles flooded. At the same time, there is a feeling that he suffocates the engine. Among other things, some motorists who do not know about the principle of operation of the internal combustion engine can close the inlet nozzle with a cloth so that water does not get into it. Funny, but it happens.

Fuel pump

If then, of course, the car stalls. The carburetor will work perfectly, that's just no one gives gasoline. On the injection vehicles, the fuel pump is located under the rear seat. On carburetor - near the camshaft (as it has a drive). If he stops working, the engine can function normally at idle, but with increasing revolutions it will definitely stall. However, with full wear of the gasoline pump, the motor will not start at all. To get rid of this malfunction, it is necessary to either carry out the pump repair, or replace it completely, which is most efficient. As for carburetor motors, they can strongly wear the rod of the pump diaphragm drive.

Electrical equipment

The problem of stopping the motor is capable of improving electrical equipment. In particular, the appearance of oxidation on the battery can occur. Although old cars, even new - all need maintenance and careful care. Consequently, the contact is worsening, as resistance increases, and this leads to the fact that the engine stalls. Also, the battery itself can be out. In the same case, if the generator does not give the necessary current, the entire electric network of the car turns into power from the battery. If you have not seen a hot lamp immediately, signing that there is no charging, the car will continue to move. With the fact that the light will be turned on, and the ignition system works, after a while the battery will completely discharge and the engine will stop. You have to charge the battery, as well as repair a fully generator.

Here we will analyze all possible reasons for which the carburetor in the car VAZ 2107 stalls. In most cases, the breakdown can be eliminated independently, but sometimes it will be necessary to complete the carburetor.

If you notice some of these phenomena in the work of the car VAZ 2107, then you should carefully check the carburetor. You may find a breakdown in it.

• If the VAZ 2107 starts and immediately stalls, the cause can be a carburetor. All subsequent attempts to start the engine will be unsuccessful.
• In cases where the engine is hard to run, you also need to check the carburetor. The car can stuck after a short time.
• If the engine stalls immediately after launch, it is also a sign of a carburetor malfunction. The engine will stroke several times, and only after numerous attempts, you can run the VAZ 2017.

Causes of carburetor VAZ 2107 breakdown

Here we gradually describe all possible reasons for the fact that the VAZ 2107 will start and stall.

If the causation of the carburetor breakdown was the lack of fuel in the float chamber, then the likelihood is that the fuel pump or the power system is also defective. Just remove the hose from the fuel-powered fitting. After that, make a pair of pressing the lever for manual fuel supply. From the hose hole should jet to water gasoline. If the jet was weak, or there was no one at all, then it is necessary to carry out a detailed check of the fuel pump and the power supply system.

Filter clogging is also a frequent cause of the carburetor breakdown. Fix this cause will be very easy. You will need to get a mesh filter, then clean it. For the purposes of cleaning it is worth using a toothbrush, or something similar to it.

You can try to wash the filter using acetone. Also can help a sphailed aircraft. Think them all the filter. Make the filter seat cleaning. Sometimes it may be necessary to fully replace this detail, but it is better to try it just to clear it.

Soler a solenoid valve or a fuel jacker of the idle system

First of all, you need to look at the position of the fuel oil and the electromagnetic valve. As a result of some breakdown, he may turn away because of which the breakdown occurs. Just trust it. Also try to remove the wire from the valve, and put it back. You must hear a characteristic click. He indicates that the valve earned. If you did not hear a click, connect the battery plus and the valve output. If you do not hear click, then it will be necessary to replace the valve. If you have a click, it is worth checking the EPHX system.

The correctness of the valve can be checked by pulling out the fuel jam. Look at it carefully. It should not have contaminated areas and damage. Look at the sealing ring and shut-off needle. The fatter should be carefully cleaned and bleed with compressed air.

This is a very extensive problem that will be hard to eliminate. Because of it, it does not always stall the car. This can occur if the fuel mixture is very strongly depleted by excess air. This is the reason why the carburetor is started and stalls in the VAZ 2107. In this case, you need to check the entire carburetor.

Especially subject to:

• Ring under the valve;
• Tube to the vacuum;
• Tube to the valve lid;
• Ring on quality screw.

Sometimes it will be easier to replace the entire carburetor.

Diaphragm damaged

If the reason is the aperture of the starter, then it will have to be fully disassembled and viewed. Sometimes it may be necessary to fully replace the starting device, but not often. It will be necessary to adjust. Be sure to replace the diaphragm to the new one.

Clogging of fuel and air jets

Emulsion wells and tubes of the dosing system can also be clogged.

You will need to disassemble the carburetor, take out the above items and clean them. For cleanings, it is necessary to use acetone, brush and sphailed aircraft. They need to be cleared of all visible contaminants. It is worth noting that in systems of seks and ozone components will be the same. Only their location is distinguished.

Cleanings require:

• Air jets;
• Emulsion tubes;
• Fuel jets;
• Emulsion wells.

You need to clean all the components, even if some of them are not badly contaminated. This will help avoid rebuilding.

Clogging of fuel and air jets of the idle system

The clogging of these sections of the carburetor can also cause the VAZ 2107 to start and immediately stalls. In this case, you will have to disassemble them. It is easy enough to do, you just need to safely unscrew the jets. Next you need to clean and blow with compressed air. Sometimes it may be necessary to replace them. You can try to clean the buses without resorting to the complete scarce of the carburetor. This will significantly reduce the cleaning time.

Disrupted fuel level in the float chamber

This is a very frequent reason why the carburetor is stalling in the VAZ 2107. This is due to improper fuel level adjustment. The fact is that the fuel mixture is disturbed. It can be strongly enriched, or on the contrary depleted. In this case, you need to adjust. It can take a long time, but so you can avoid carburetor faults.

Not adjusted by SUPPLY

Due to the fact that the air damper can not be completely open, the fuel can enrichen. Most often it does not lead to serious problems, but sometimes fuel is enriched as far as the engine is very difficult to start. Especially if it was heated with a long ride. In this case, it is worth adjusting the air damper (suction). Sometimes a strongly enriched mixture may even pour candles.

With the proper operation of the air damper, it must overlap the cross section of the right chamber. This happens if the handle is completely elongated. And if the handle is drowned, it should get up vertically. If this does not occur, it means that the cause of the carburetor breakage is precisely in improper adjustment of the supply. His adjustment should not take a lot of time.

Other reasons why VAZ 2107 stalls

VAZ 2107 may stuff not only because of the carburetor. This can occur due to breakdowns of other systems. First of all, pay attention to the ignition system. Its breakdown can often be confused with the carburetor breakdown. This is due to the fact that the signs of the ignition system malfunction are very similar to the signs of the carburetor malfunction. You still need to check the power system. It may also be the reason that the VAZ 2107 will start and immediately stalls.

conclusions

Most of the above causes can be eliminated independently. To do this, you just need to clearly follow the instructions. Most often you only need to clean some parts of the carburetor, but sometimes it may be necessary to complete the carburetor in the VAZ 2107 car. So you quickly get rid of many problems associated with the fact that your car starts and immediately stalls.

Hello everyone today want to talk about the reasons, because of which your car VAZ 2107 stalls, and in connection with this unpleasant annoyance you can no longer continue to move on your iron horse. Today we will try to consider the main reasons why your engine stalls. Of course, a lot of such reasons are quite unfortunate.
The first reason is the problems with the idling regulator (RXX) usually the machine stalls at idle. RHX may fail due to contamination, and this leads to the fact that the rod clinite. To make sure you need to remove the RCH from the seven and in the case of pollution is rinsed well. It is advisable to use a liquid that blends oil well.

The second reason, due to which the VAZ 2107 stalls is alarm system (unless of course it is installed) In most cases, the alarm system works with electric chain of the fuel pump, and where do you ask? And despite the fact that the unscrupulous mechanic who connected you the alarm could make his job from here and could follow problems. Especially if they did everything on twists, then over time she weakens, and write everything as they say. Power supply to the pump ceases to act, as a result of which VAZ 2107 will not start.

The third reason is a too rich combustible mixture. You can check this version by unscrewing the candles if the contacts of the candles are covered with black nagar it means that the mixture is too rich. For how much gasoline is supplied to the cylinders, corresponds to the position of the throttle valve, as well as the readings of the temperature sensor, by car VAZ 2107 this sensor is located on the left in the rear of the block head. If there is a need to replace the temperature sensor, then you have to merge what, then part of the antifreeze.
The failure of the mass flow sensor (DMRV) on the VAZ 2107 also leads to the enrichment of the mixture. You can check the DMRV operation using a multimeter. If the voltage is more than 1,002 volts, it will have to be replaced.

The fourth reason is a strong depletion of a combustible mixture. As a result, your "seven" will also slander. This is mainly due to air supply. The main seats of the supply are inlet system, or weakening fastening in places where they cost. To search for air suction, a smoke generator is usually used to see the place where the smoke is drawn.

And the fifth reason is a vacuum brake amplifier. Since the air seats can pass through it. This happens due to a leakage diaphragm. You can change the faulty vacuum on the VAZ 2107 by moving the hose that connects the vacuum amplifier and the intake manifold if the engine does not heat up then, most likely it will have to change the vacuum.

Well, that's all we looked at the main reasons why the VAZ-2107 car stalls, if you had other reasons, then write in the comments. So far.

Situations when the VAZ injector is immediately started, after which it stalls immediately, it happened quite often. And all because of the fuel injection system (forced type). To correct this situation, auto owners often use a heating candle, but this is not a solution to the problem, but only a temporary measure. If the VAZ 2107 starts up and stalls immediately after turning the key in the ignition lock, then in most cases it indicates a problem in the delivery of fuel (scored or runs incorrectly fuel pumps), or the quality of the fuel used leaves much to be desired, and the nozzles are simply scored. And the car starts solely on the residues of fuel in the cylinders.

Search for defective component

So, what do you need to do if the engine is easily started, but after that it immediately drops turns and stalls? First of all, you need to check the availability of a car on candles. If some of them are covered with a layer of Nagara, the engine a priori cannot work normally. It first starts due to the movement of the starter, but immediately it slows down, since several cylinders physically cannot withstand the entire load from the crankshaft. The carburetor, by the way, may also fail because of such a problem.

So what is the cause of the engine malfunction? If the machine starts, then, at least, everything is fine with spark. That is, the electrician works as it should be. It will not be superfluous to unwind the heads and try to find those candles that are covered with a layer of Nagara. It is possible to cleaned them with the help of burning over the gas burner and cleaning alcohol (it can only be done when the contacts are cold).

The injector itself can also clog. In this case, simply does not work fuel supply to the combustion chamber. These actions should be made:

• remove blocks and check the dampers;
• check the operation of the sensors;
• check whether the engine is working normally at a temperature of over 80ºС.

Naturally, the fuel pump itself can be harmful. In the injector at the time of launching the motor, it is rotten by automaton at the expense of the starter, and then it goes from the generator. If one of these components work incorrectly, the machine is simply stupid. Here again we are talking about the residual amount of fuel in the cylinders. If the motor immediately stalls, and the starter is unevenly working with it, then, most likely, the problem or in it, or in the ignition lock.

You should try to replace it with an obviously good and re-test the operation of the engine. In the extreme case, contacts are simply clamped.

What if the problem is in the ECU?

The engine may not work incorrect if the on-board computer works. In VAZ, it is he who is responsible for the timely supply of fuel, synchronization of the operation of the injector nozzle and spark plugs. When the engine immediately stalls, this indicates the mismatch of the moment of supplying fuel and the ignition of the fuel mixture.

As a rule, helps changing the firmware or restoring it to the factory state. Although sometimes it may be simply necessary to adjust the fuel supply cycle, as well as the saturation of the mixture. In extreme cases, the VAZ 2110 (or later model) will have to replace the entire unit of the ECU or turn it off, translating the engine into operation mode only from mechanics.

It should be noted that the engine is responsible for the operation of the engine, but also a bunch of sensors, which is regulated by the pressure in the nozzle, the saturation of the mixture, the moment of ignition.

That is, you need to check and their work. Although, when identifying a malfunction of one of them, a Check Engine signal should be applied to the dashboard. So, for example, happens when the VAZ 2110 starts. This does not occur only if the ECU simply does not receive signals from the sensors. It is worth noting that in the model 2107 by default the computer does not put, but the injector does not work without it.

Similar problems arise and then when the carburetor is synthetically reworked under the injector, but it is left to the former on-board computer. It simply change the firmware, plug new modules, but you need to understand that it is originally not designed for such a job. Thus, if the carburetor is reworked, then with it you need to change both the ECU on the compatible model. Fortunately, VAZ took care of their release.

So, if the injector is starting and immediately stalls, then the main reasons for such a malfunction are disorders in the operation of electronics (including the ECU), the incorrect operation of the fuel system or the gasoline filtering problem. To identify the main reason is not problems. In extreme cases, you can always contact the center of a hundred. But it is worth remembering that any adjustments to the operation of the on-board computer can be entered only with a fully suitable engine.

In this article we will talk about such an unpleasant problem as the engine stop, as well as bad launch. Consider the main reasons why the engine is stallped at idle and on the go. In addition, let's talk about why the motor does not start on hot, as well as about the solution to each of the problems described above.

Common reasons for which idle is stolen:

1. The most common is - a no-power regulator (sensor), which is directly related to idle engine speed. Check in it whether the breakdown is quite simple. If the machine does not start when you twist the starter, work the gas pedal, the engine must start. If the turns start to swim immediately after you removed the leg with the pedal - 99% what is the reason in the idle regulator. The decision -, for this, the owners of vases will take at least time.

2. The second probable reason why the engine is stalling at idle - problems with throttle valve. This trouble is treated - banal.

3. If after cleaning the problem is preserved, we assume that the reason for which the motor is stalling at idle turns can be DPDZ (throttle position sensor). The problem is solved by, the procedure is not complicated and actually performing with your own hands.

There are no cases when the engine stalls on the go, as they say so much. Below will be listed the most likely and most often occurring reasons for which it can occur.

Motor stops on the go - reasons

1. Embossed fuel is the first thing that comes to the head of the majority of us, besides, it is necessary to start looking for the cause of the engine stopping on the go. You are "lucky" if it happens immediately after refueling, in this case it is safe to say that the problem is in fuel. Treated with fuel and fuel.

2. Candles. As a rule, the suspected suspicion is most often falling, after a bad fuel, of course. Here everything is simple - unscrew the candles and check their condition, if necessary.

3. Fuel filter. The order of the scored filter can cause a fuel supply interruption, as a result of which you gasut, and the engine stalls on the go. To troubleshoot a malfunction sufficient.

4. Air filter. All the same as with the fuel, if clogged, then the air does not come, therefore the fuel and air mixture comes out of convexed and the candle is simply poured. In addition, a motor shortage of air will be given, that is, power will fall, and the combustion process of the mixture in the cylinders will not be able to be carried out, in the end the motor will be stuck. To eliminate this malfunction, it is enough to replace the air filter.

5. Faulty gas station - the second "suspect". If your fuel pump is not all right, then the car will behave this way, it will be stuck on the go or the engine will not start at all. The problem is solved by checking the pump, its repair or.

6. Battery. The oxidation of battery terminals or bad contact can lead to engine stop. Check the terminals, if necessary, clean them or replace the battery.

7. If the engine strokes on the move and the generator can also become a reason for the cause. The generator failed does not charge, as a result, the side network of the car is powered exclusively from the battery, and it is not enough for a long time. As a result, you are not suspecting that the car is working on the battery, continue to move until it is completely discharged. Treated - and.

6. In advanced auto, reasons can also be with electronics and various sensors. If not strong in this and all of the above nodes and parts are normal, then it is better to turn to the specialties, and then you can replace the floor with the floor of the press ...

Why the engine stalls on the hot, Does it start a well-hot engine?

1. The first reason is. During the movement through it, a large number of air passes because of which the carburetor is seriously cooled, at the same time cools and fuel that passes through it. As a result, the temperature of the carburetor is several times lower than the motor temperature. Because of this feature, problems arise, after a long journey you are jamming the engine and makes a short stop, at this time the carburetor begins to heat the hot engine housing. The remains of gasoline in a high-temperature float chamber begin to evaporate, filling emptiness - air filter, intake manifold and actually the carburetor itself. Aerial traffic jams are formed, and there is no fuel drop in the float chamber.

The solution to the problem is quite simple - press up to half the gas pedal several times and try running the engine. By this you make a mixture poorer and release excess evaporation. It should be noted that problems with the launch of hot can also be due to a similar problem, only the fault of the fuel pump or fuel line. This, as a rule, occurs in the heat, when air traffic jams that prevent the flow of fuel in the carburetor are formed from evaporation in the fuel system or pump.

2. The second possible reason for the strange behavior of the heated engine - problems with the starter. Make sure that when you try to start the engine, the starter twists, and not just clicks or does not respond at all. If this is the case and one of the above options was confirmed. You need to check the starter. If you are on the road, then checking can be reduced to the elementary test of the starter feed wire or other visual operations. If you got home, make a detailed. In the event of a malfunction or replacement.

3. As an option, the reason when the engine does not start on a hot can be a terrestrial battery due to the above, when the generator did not give charging and the battery completely sat down.

Well, it seems to have missed anything!? Today, all, we hope the article will help, tell you the cause of the breakdown and help in solving your problem if you know other reasons, as well as how to solve them, you can add an article using the form for comments. Thanks for attention.
