Checking The Component And Wiring

Read off the fuel pump (FP) load (signal from the engine control module (ECM) to the fuel pump (FP) control module).

Check that the signal is approximately 50% (±10 %) with the engine idling at operating temperature.

Check the cable between engine control module (ECM) terminal #B20 (#C20) and fuel pump (FP) module terminal #1. Check for a short-circuit to supply voltage.

Remedy as necessary.
