Checking the status

Check whether the fault is permanent or intermittent by checking the value of 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 35% (5%) with the engine idling at operating temperature.

The fault is permanent if the signal is incorrect or the engine will not start.

The fault is intermittent if the signal is correct.
