Cut-Off Relay
- Remove fuse box panel mounting bolt and nut. Pull down panel and remove fuel pump cut-off relay. Turn ignition switch to "ON" position. Connect positive probe of voltmeter to Black/Yellow wire terminal of fuel pump cut-off relay connector. If no voltage, check fuse and continuity of Black/Yellow wire.
- If voltage is present, check Blue wire at cut-off relay for battery voltage. If Blue wire does not show battery voltage, check for continuity between connector and negative side of coil.
- Turn ignition switch to "OFF" position. Attach jumper wire between the 2 Black/Yellow wires of connector. Turn ignition switch to "ON" position.
- If fuel pressure is now available and battery voltage was present at Blue wire, replace the cut-off relay. If no pressure is available, unplug fuel pump leads at pump.
- Attach positive lead of voltmeter to the Black/Yellow wire and negative lead to Black wire. Battery voltage should be present with ignition on. If not, check continuity of Black/Yellow wire from relay and Black wire to ground.
