Fuel Pump Circuit

  1. Turn ignition on. Connect a jumper wire between fuel pump check connector terminals (Black and Green/Red wires). Fuel pump check connector is located on firewall, under windshield wiper motor.
  2. Listen for fuel pump operating sound. If there is no sound, check main fuse, inertia switch (located at left rear shock tower), circuit operating relay, fuel pump and all electrical connections. Airflow meter grounds circuit opening relay, and operates fuel pump whenever air flow is present.
