Checking The Component And Wiring

Check the connector for the fuel pump (FP) control module. Check for contact resistance. Check for oxidation.

Check the signal cable. Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.

Take readings between:

• Engine Control Module (ECM) #B21 (#C21) and control module fuel pump #5.

Remedy as necessary.

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