So, the first cause of engine failure is a fuel supply failure. This may be due to the fact that the electric fuel pump is not functioning or there are some problems in the gasoline pressure regulator. The fuel filter may also be clogged or there may be no fuel in the tank at all. In this case, you need to check whether the fuse is in a normal state, whether the EBN connectors, its relay, and the starting relay are in good order. When the ignition is turned on, it is important that the engine makes a characteristic sound. So, if this problem really exists, then you need to replace the fuel pressure regulator or filter, and then pour gasoline into the tank. Also, it will not be superfluous to check the he alth of the connectors.

Also, if there is a suspicion of an engine malfunction, look for problems in the ignition system. Perhaps there is no contact in the electrical circuit, or the ignition coil is simply faulty. In this case, you need to check if the fuse is intact. The ignition coil may need to be replaced.

Also, engine malfunctions can be caused by water entering the fuel tank. Or he could simply refuse to work with any of the engine cylinders. In this caseyou need to drain the sediment from the fuel tank, check for serviceability of the connection and troubleshoot. It is advisable to clean the carbon deposits and replace the candles and their tips.

So, in order to identify engine malfunctions, you first need to pay attention to whether it runs smoothly, whether failures occur when you partially or fully press the pedal. And if there are any noises in the engine, then this also indicates a malfunction. The easiest way, of course, is to identify the problem if the engine does not work well in all modes.

It is worth listing the malfunctions of the diesel engine. Many, acquiring such a mechanism, pay attention only to the small consumption of relatively cheap fuel. Undoubtedly, diesel engines are reliable. Their shortcomings are associated only with production technology, they appear only with runs that exceed the specified resource, or with illiterate use. The global problem is non-compliance with operational regulations. Oil needs to be changed once every 7,000 kilometers traveled, otherwise it will oxidize, and this will negatively affect engine performance.

Faulty injection engine also deserve attention. Most often, these problems are associated with the crankshaft position sensor. If it breaks, it will not allow you to drive more than five meters. If the fuel pump fails, leaving is also unrealistic. Here the reasons may lie in the presence of water and dirt in gasoline. If any of the othermechanisms or sensors, then the engine will work - its installation will simply switch to the emergency program. It is difficult to drive if there is a problem with the throttle position sensor. However, do not expect a complete breakdown. If the car is dear to you, you need to immediately repair it.
