VAZ 2107 The engine starts up and stalls. After starting the engine, it stalls immediately: why is it happening. Clogging of fuel and air jets of the idle system

the main / Battery

During the operation of the car, a frequent situation is that after turning the ignition key, the machine starts, the engine begins to work and stalls after a few seconds. As a rule, it takes 3-5 seconds from the moment of launch. Before complete motor stops are also noticeable, the power unit shakes, works very unstable.

This occurs as a result of reducing revolutions, resonant effects of rotating, etc. When you try to start the engine, the motor can no longer run or the situation described above will repeat again.

The reasons for this problem are different. The main thing is if the car started and stalled, it suggests that in-depth diagnosis is needed. Next, we will talk about what to do in such a situation, as well as how to find the reason why the motor stalls after launch.

The engine starts and stalls: troubleshooting

So, if a similar problem manifested itself, then a number of features should be taken into account. First of all, the operation of the DVS after the launch will affect the following factors:

fuel supply;
air supply;
spark on (for gasoline engine);
correct work (for diesel engines);
good work and electronic sensors;

The synchronous operation of the valve mechanism may be violated due to the fact that the belt or the timing chain can be incorrectly installed, stretched, wear out and are able to jump on the pulleys. As a result, the discovery and closing of intake and exhaust valves does not correspond to the engine operation stations.

In this case, to troubleshoot the problem, you must check the specified elements by tags and perform other necessary procedures.

Failures in the work of the ECU are less common, but such an opportunity should not be excluded. Additional attention deserve cases when the controller reflash, was performed, or installed on the car.

As for different sensors, attention should also be paid to and, as well as an oxygen sensor in the exhaust system (lambda probe). If on the dashboard during a short-term launch of the FEF or no signs of problems are not visible, you still need to perform.

The specified diagnostics can be made. To do this, you need an adapter in, which will allow you to read error codes and display the information received on the tablet, laptop or smartphone screen.

That in the end

As can be seen, there are quite many reasons why the engine begins to work and stalls after launch. At the same time, most of them are usually associated with the fuel system, the ignition system and the electronic control system.

It is also important to take into account that the occurrence of piston rings can lead to certain difficulties during the launch and to stop the motor after the start of work. Less often, the problem arises due to the significant common wear of the engine.

In this case, it is appropriate to talk about due to the fact that the engine worked its resource (the walls of the cylinders, rings, etc.), that is, the unit needs overhaul. Compression can be measured on a service station or by the compressometer.

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.

The owners of VAZ 2107, 2110, 2112, 2114, and other cars, may face a problem - the car starts and immediately stalls. The engine starts, but after a few seconds, turns fall and the engine stalls. Consider the possible causes of launch fault, and ways to eliminate them.

To begin with, consider the most common problems.

Completed gasoline (diesel fuel). No matter how paradoxically sounded, but often drivers forget to follow the level of fuel in the tank.
On diesel engines (especially in winter) the reason that the car started and almost immediately stalled, it can become frozen fuel (but usually diesel vases are a big rarity).
Quality of gasoline At the refueling is often terrifying, so reflecting the car with low-quality flammable, you can face the problem of the storm engine. If bad gasoline is a bit, you can dilute it good. But if the full tank is flooded, it is better to merge the surrogate from sin away.
Worn wires and old (faulty) candles Also quite often cause.
Engine compression, More precisely, its absence can provoke a situation at which the engine stalls barely time to "pick up". But this is already a very serious breakage, the appearance of which is accompanied by a mass of other symptoms, not to notice which during the operation of the car is simply impossible.

VAZ with an injector to start and sruzo stall

A few reasons:

Injector cars can behave so because of the fuel pump malfunction. It is in the tank. Checking its performance is very simple. If you turn the ignition key in the first position and listen, it will be heard as a pump running, nervous gasoline into the system.
Strong fuel filter pollution Thin cleaning can also lead to the fact that the car stalls after the start. The filter simply does not have time to skip the required amount of gasoline.
ECU errors often often lead to problems with the start of the engine, not receiving signals from certain sensors, or yielding them in a distorted form. The diagnosis of such breakdowns is best done in specialized services.

Causes for which carburetor machines are harvested

If the machine starts and immediately stalls, then the problem may be associated with the lack of fuel in the float chamber. You can try manually pumping the fuel pump. It needs to be checked for performance, and, if necessary, replace. Before engaged in self-purification of the power system in general and the carburetor in particular, it should be remembered that any unconscious manipulations can lead to a large increase in fuel consumption.
Another reason why the engine stalls - the mesh filter was clogged in the carburetor before its entrance. If the machine starts up and stalls after a few seconds because of this filter, then it must be cleaned and washed. To do this, use a toothbrush and solvent (gasoline or acetone). After that, right there, together with the filter, clean the socket in which it is inserted.
It happens that in the VAZ cars after a few seconds after launching turns are falling due to the malfunction of the solenoid valve.. The check is made as follows: the valve is twisted, power is supplied to the plus contact, and the housing is closed on the motor weight. With the correctness of the valve, a distinct sound will be heard, and the needle will go into the case.

You can simply wire connected to the valve and put it in place. If the click is not audible, the valve is faulty. Unscrew the valve and get a jiggle from it. If he bent, it needs to be replaced. Make sure that the valve locking needle is moving freely, and the valve gasket is not torn, and it fits tightly to the case.

If the valve click is present, then the EPHX system needs to be propagated. It may need to clean the fuel jawer of idling. If the speed of the car engine is falling, its clogging can affect the stability of work. To clean the gibera, you need to create an increased discharge in the channel channels.

To do this, we bring the car and raise the revolutions to 3000. For several revolutions, we turn the jiggle holder (electromagnetic valve). This allows you to create the required discharge in the channels. We repeat the procedure several times.

What else can be breakdown VAZ 2107

Another common problem, which is started and stalls the car VAZ 2107 engine - getting into an excess air carburetor. In this case, the fuel mixture cannot support the engine operation for a long time, and the car, though it started, stalls after a few seconds. It is necessary to determine the location of the air of the air and eliminate the gap.

It happens, the jackets and nozzles of the dosing system are clogged. This also affects the drop of engine speed, so that the VAZ 2107 stalls after a few seconds. What to do in this case? You need to unscrew the jets and nozzles under the cover of the carburetor and clean them. After that, blow the wells and jets with compressed air. If you have a carburetor Solex, then you need to clean and blow up the fuel jets located on the bottom of the wells.

Solex carburetors problems

In addition to the listed, the engine turnover is falling, if the fuel level is incorrectly adjusted in the carburetor (float chamber). As a result, the fuel mixture either lack gasoline or it is too much. When adjusting the carburetor VAZ 2107, it does not need to be disconnected from the engine.

Follow these steps:

remove the air filter body, unscrewing all attachments;
remove the carburetor cover;
check the position of floats. To do this, divide and reduce them together to achieve the right location.

It is necessary to achieve such a position of floats so that they can be easily moving, not clinging the walls of the camera in which there are. It will not be superfluous to measure the distance from the protrusions on the float to the paper laying. The distance must be within 0.75-1.25 mm. Use probe to measure.

What if it is far from the norm? In this case, you need to adjust the height of each of the floats.

As we saw, the reasons why the engine stalls is not so little. To properly start the engine, check and eliminate all the above faults. After, if the problem did not decide, you will have to refer to the specialists.

What if you start and stall injector VAZ at idle? Most of all, this problem concerns old cars, as various contamination in the fuel system and B are accumulated with age, and sensors and mechanisms are wearing - all this will inevitably lead to changes in the engine operation.

In order, we describe all the reasons that lead to this problem.

First of all, the inspection is subject to a mass flow sensor (DMRV). The sensor element of the sensor is polluted and wear out with age, which is why its rest voltage grows, and the time of its reaction to changes in the air flow increases. If the voltage is exceeded 1.035V, it is worth thinking about replacing the sensor, because it will no longer be able to give overestimated air flow testimony. The electronic control unit will supply more fuel and the mixture will be re-engaged - and this will affect very badly on all modes of engine operation, as well as to idle stability.
The idling regulator (RXX) can also affect the stability of the engine. Singing rod - the most typical malfunction in it. In addition, with age, natural wear of the regulator components occurs, and this leads to problems with the movement. The usual service life is 100-150 thousand km. Only with the help of special equipment can be checked RXH, and it is better to replace it with a new one if a malfunction is suspected.
Very often enough to simply clean the throttle knot from pollution. It is easy to do it yourself. These are the most basic cases that need to be paid attention to. Next will go atypical situations.
Sometimes the problem is in the leakage of the intake manifold. You need to check the gaskets, vacuum hoses, sealing rings nozzles, and a vacuum brake amplifier and a collector stub. It is easiest to find the air seats with a smoke generator.
Pay attention to the fuel pressure.
You also need to check the ignition and candle system in particular.

In conclusion, it should be noted that without special equipment, a complete check of the system is impossible. Only with it can be accurately identified a malfunction.
