Circuit/System Testing

Verify that DTC P0562 is not set.
- If DTC P0562 is set, refer to DTC P0562 (ECM) or DTC P0562 (FSCM) .
Ignition OFF, disconnect the harness connector of the K27 fuel pump control module.
Ignition ON, test for greater than 11 V between the IGN voltage circuit terminal 15 and ground.
- If less than the specified voltage, test the IGN voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ABS/VSES fuse is open, test the voltage circuit for a short to ground. If the circuit tests normal, test or replace the Run/Crank relay.
If all circuits test normal, replace the K27 fuel pump control module.
