Checking the fuel injection system

If there is a malfunction in the fuel system, first check that all electrical connectors are securely connected and protected from corrosion. Also check the cleanliness of the air filter, the condition and gap in the spark plugs, the correct adjustment of valve clearances, the compression in the engine cylinders, the setting of the ignition timing and the cleanliness of the air supply hoses to the engine.

If the initial actions do not help to identify a fuel system malfunction, then it is necessary to have the fuel system checked and repaired at a service station.
