Checking Components

Check that the fuel level in the tank is not too low (almost no fuel).

Check the connectors between the pump control module and the fuel pump (FP). Check for contact resistance and oxidation.

Check the fuel lines and fuel filter for blockage and leaks.

Remedy as necessary.

Try a new fuel pump (FP) if no fault is found during the above fault-tracing.

HINT: The diagnostic trouble code (DTC) can also be caused by a defective pump control module.
