Check the pressure in the fuel system of the engine
Check the fuel pressure in the fuel rail of the engine is possible only with a pressure gauge with a set of adapters for connection to the fuel pipe. 1. Turn on the ignition and listen: in a few seconds you should hear the sound of elektrobenzonasosa. If it is not heard, check the electrical power supply circuit elektrobenzonasosa.
A WARNING Keep in mind that elektrobenzonasos not turn on if the system has a fuel pressure. In other words, if you have previously included the ignition and tried to start up the engine, the defective elektrobenzonasos have had to create pressure in the system and its failure to include in this case is not a malfunction. |

The possible reasons for the decline of pressure: - Faulty fuel pressure regulator; - A clogged fuel filter; - Faulty fuel pump.
