Malfunctions of the engine: how to identify and eliminate?

So, the first reason for the engine malfunction is the fuel feed violation. This may be due to the fact that the electric fuel pump does not work or there are some malfunctions in the gasoline pressure regulator. Also, the fuel filter may be clogged or the fuel is not present at all in the tank. In this case, it is necessary to check whether the fuse is in the normal state, if the connectors of the EBC, its relay, and the start relay are working. When the ignition is switched on, it is important that the engine emits a distinctive sound. So, if this problem really exists, then you need to replace the fuel pressure regulator or the filter, and then pour gasoline into the tank. It will not be superfluous to check the serviceability of the connectors.

In addition, if there is a suspicion of engine malfunction, note the malfunction in the ignition system. Perhaps there is no contact in the electrical circuit or the ignition coil is simply faulty. In this case, it is necessary to check if the fuse is intact. Maybe you need to replace the ignition coil.

Also, engine malfunctions can be caused by water entering the fuel tank. Or he could simply refuse any of the engine cylinders. In this case, you need to drain the fuel from the fuel tank, check for serviceability and repair the problem. It is desirable 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 works smoothly, whether crashes occur when the pedal is partially or fully pressed. And if there are any noises in the engine, it also indicates its malfunction. The easiest way, naturally, to identify the problem, if the engine in all modes is working poorly.

It is worth mentioning and faults of the diesel engine. Many, buying this mechanism, pay attention only to a small expenditure of relatively cheap fuel. Undoubtedly, diesel engines are reliable. Their shortcomings are associated only with the technology of production, they are manifested only with the mileage that exceed the specified resource, or with illiterate use. The global problem is the failure to comply with the operational regulations. The oil needs to be changed once in 7000 kilometers traveled, otherwise it will be oxidized, and this negatively affects engine performance.

Malfunctions of the injector engine are also noteworthy. Most often, these problems are related to the crankshaft position sensor . If it breaks, it will not allow you to drive more than five meters. If the petrol pump refused, it's also impossible to leave. Here, the reasons may lie in the presence of water and mud in gasoline. If any other mechanisms or sensors are faulty, the engine will work - its installation will simply go to the emergency program. It is difficult to move if there is a problem with the throttle position sensor. However, do not expect a complete breakdown. If the car is expensive, you need to immediately repair it.
