- Remove rear seat. Remove fuel pump access cover. Ensure ignition is off. Disconnect 3-pin connector from fuel gauge sending unit. Connect voltmeter positive lead to terminal "A" (Yellow/White wire) and negative voltmeter lead to terminal "B" (Black wire).
- Turn ignition on and observe voltmeter. Voltmeter should indicate 5-8 volts. If 5-8 volts are indicated on voltmeter, go to step 3). If no voltage is indicated, check for blown 7.5-amp fuse No. 23 in the dash fuse box. Check for open in Yellow, Yellow/White or Black/White wire. Check for poor ground.
- Turn ignition off. Attach jumper wire between terminal "A" (Yellow/White wire) and terminal "B" (Black/White wire). Turn ignition on. Gauge needle should start moving toward "F" mark. Turn ignition off within 5 seconds or before gauge needle reaches "F" mark on gauge. Failure to turn ignition off before needle reaches "F" mark may damage fuel gauge.
- If fuel gauge needle does not move, replace fuel gauge. If fuel gauge tests okay, test fuel gauge sending unit.
