Checking Components
HINT: The fault may be intermittent or be due to the flow capacity in the system being too low.
Check that the fuel level in the tank is not too low (almost no fuel).
Check the fuel lines between the fuel pump (FP) and the fuel rail for the injectors for leakage.
Check the fuel pressure sensor connectors. Check for contact resistance and oxidation.
Check the connector for the fuel pump (FP) control module. Check for contact resistance. Check for oxidation.
Check the fuel lines and fuel filter for blockage.
Remedy as necessary.
Try a new fuel pump (FP) if no fault is found during the above fault-tracing.
