Cut-Off Relay

  1. Remove fuse box panel mounting bolt and nut. Pull down panel and remove fuel pump cut-off relay. Turn ignition switch on. 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.
  2. 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.
  3. Turn ignition switch off. Attach jumper wire between the 2 Black/Yellow wires of connector. Turn ignition switch on.
  4. 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.
  5. Attach positive lead of voltmeter to 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.
