Fuel Gauge: 3.5RL

  1. Check METER fuse (7.5-amp) located in underdash fuse/relay box, behind left kick panel. Check METER fuse (15-amp), located in underhood fuse/relay box. Check gauge relay located at relay box, at left front of engine compartment. See GAUGE RELAY  under COMPONENT TESTS. Remove rear seat cushion. Remove fuel tank access cover. Disconnect 3-pin fuel gauge sending unit connector.
  2. Using DVOM, check for voltage between fuel gauge sending unit 3-pin connector terminal No. 1 (Black wire) and terminal No. 2 (Blue/Green wire). Turn ignition switch to ON position. If 5-8 volts exists, go to next step. If 5-8 volts does not exist, check for poor connections or open in Blue/Green wire or Black wire between fuel gauge and fuel gauge sending unit. Check for open in Black wire between fuel gauge sending unit and ground connection G652. Ground connection G652 is located at left front corner of trunk. Also check for open in Blue/Green wire between fuel gauge sending unit and instrument cluster. See WIRING DIAGRAMS . Repair as necessary.
    3. NOTE: If fuel gauge is of the type that continuously indicates level even when ignition switch is off, pointer will move slower to "F" mark.
  3. Turn ignition switch to OFF position. Connect a fused jumper wire between fuel gauge sending unit 3-pin harness connector terminals No. 1 (Black wire) and No. 2 (Blue/Green wire). Turn ignition switch to ON position. If fuel gauge pointer does not move toward "F" mark on gauge, replace fuel gauge. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. If fuel gauge pointer moves toward "F" mark on gauge, check fuel gauge sending unit. See FUEL GAUGE SENDING UNIT  under COMPONENT TESTS.
