Fault of VAZ-2110: no spark. The injector 8 valves: possible causes of the problem

All of the possible breakdowns of cars VAZ-2110 are divided into three types. This is a problem in the fuel supply system, various failures in electronics and electrical engineering, as well as more global trouble (ice box). If you have problems in the ignition system, then immediately diagnosed – lost spark. Let's look at why the VAZ-2110 no spark (injector, 8 valves). So, what are the reasons of such a failure?

Possible causes of absence

Most modern cars are equipped with many sensors. They facilitate the life of car owner and make the repair. In electronics, responsible for the operation of a fuel-injected engine has several sensors that are responsible for the process of sparking. But the reasons that no spark (VAZ-2110, the injector 8 valve), can be in other nodes. There are several types of possible faults. The first can be attributed to various problems in the fuel system of the vehicle. This includes malfunctions in which fuel cannot get into the cylinder or supply is carried out correctly.

If there is no spark (VAZ-2110, the injector 8 valves), it might be related to the fuel system. Often fails pump relay itself or the immersion element. Validation is performed “hearing”.

Then there are the problems associated with the electrical part. This is one of the most common problems. When such damage to the spark comes electric discharge. Naturally, the mixture will not be ignited. Among global issues – complete motor failure, broken timing belt. These faults in detail is not necessary.

Diagnostics

Why it's missing spark (VAZ-2110, the injector 8 valves)? The problem should find out the maximum carefully and in several stages. And to search for the cause was successful, you will need a multimeter and a spark gap.

Step one

Typically the symptoms are the following: the starter is spinning correctly in its standard mode, and the engine does not want to start. One of the probable reasons – a fuel pump that will not start. By the way, on injection “dozens” he submerged and placed directly in the tank.

Check the item's availability sound work. Turn on the ignition – must be a drone in the back seats. Sometimes it is not. In this case, you should check the fuses. VAZ-2110 – fuel injected cars, and the fuse box is located here on the side of the centre console on the front passenger side. You must Unscrew the fastener, then remove the lid, check the fuses on the performance and, if necessary, replace them. If the elements are fully serviceable, then you need to check whether to include relay, and both main and fuel pump. The moment when you can feel with your finger. Also you will hear a click.

If the fuel pump is operable with the help of a manometer to check the presence of fuel in it. If the gauge is missing, then click on the spool at the end of the fuel rail. This element can have a protective cap. The pressure will be quite noticeable, although the power will not be identified. Running pump and the missing pressure may indicate obstruction of the fuel line. This may be due to a clogged fuel filter.

Step two

If the VAZ-2110 no spark (fuel injected 8 valve), then often the cause is spark plugs. Naturally, they check if the fuel pump is working. It is best to test to use a pinch. If the current will be distributed over the two candles, there is a breakdown by “the ground”.

There is an option when there is a break in the wire to the ignition coil, or there were gaps in its winding. If the car VAZ-2110 no spark (the injector valves 8) two wires, the reasons can be broken in the ignition coil or the controller. In two cases, there is a probability of rupture of high-voltage wires. This option is worth checking out first. Look at the resistance level. Normal values up to 200 ohms.

Module and ignition coil

Here you can check error codes on the car. If the ECU has no diagnostic capabilities, should install a known good module.

To Find out why no spark on VAZ-2110 (injector, 8 valves), it is possible for the faulty controller. It is also possible to break the wires from the controller to the ignition coil. If there is no spark on each of the coils, is to check the availability of food. If the electric discharge not, for some reason, then the component should be replaced. The system is running the ignition module. Therefore, it is useful operation is to check the “minus”.

Possible errors of injectors VAZ

The Codes can indicate malfunctions of any parts in the car. Most often this is due to the sensors. Particularly affected are temperature sensors – they overheat. Motorists also complain about the atomizer. Problems appear due to breakages in the chain. As a result, they cannot get to work. This can be attributed topopular damage on VAZ-2110 – no spark. The injector 8 valves can't get worked up about it.

Now the error associated with engine. The most common of them are – overheating. Also overheat and spark, so the spark is lost. As a result, the motor shows no signs of life. Next, you should consider the valves. These items can be too dirty, which will lead to their complete closure. They do not pass the required mixture of air and fuel. And finally, fans – if they're not working, then the power unit will constantly overheat.

Other problems

If the starter is not rotating, the spark disappears between the ignition switch and the element. This often happens when a weak or dead battery. A good battery when testing shows no less than 11,8 V. Faulty cylinders spark will manifest itself immediately in the moment when the driver inserts and turns the key. If you turn the key too light or heavy, you need to replace the lock. The starter relay or the ignition system is also one of the possible reasons for the lack of spark. But check these sites alone will not work. The starter can jam “pull” device. In this case, the spark is lost along the way. Motorists with the experience to hit the starter with a wrench or hammer, to return the spark. But this is true only in the field.

What to do if there is no spark in the car VAZ-2110? To check the starter in the garage with the battery. If you press the device to the “minus” battery, and wire “plus” stretching to “pull”, then the device comes to life. Often the spark may disappear where the starter is receiving power. This chain is best to check with a multimeter. Can't do it alone – the assistant will work with the key at the time of measurement.

Conclusion

When the VAZ-2110 (injector) missing that spark, the reason, at once difficult to define. Perhaps the problem lies in the banal oxidized contacts. In some cases the situation can be corrected by cleaning the terminals of oxides. Especially pay attention to the wire from the mass that goes to the battery. In 80 percent of cases, the problem with hard start solved that way.
