- Disconnect fuel gauge sender wire and connect Gauge Tester (J-24538-A) between sender wire and ground. Turn ignition on. If gauge responds but not accurately, go to next step. If gauge does not respond, go to step 3). If gauge responds accurately, go to step 5).
- Remove gauge and check for loose nuts at gauge terminals. If nuts are loose and gauge reads between 1/4 and 1/2 with 90 ohms from tester, tighten nuts and install gauge. If gauge is still inaccurate and nuts are tight, replace gauge.
- Disconnect front body connector. Connect tester to lead that goes to gauge. If gauge responds accurately, check wiring between rear compartment and front body connector. If gauge does not respond, go to next step.
- Remove gauge. Check for bad connections at gauge terminals or instrument cluster connector. If connections are good, replace gauge. If bad, repair connections and install gauge.
- Check rear compartment connector and wiring to sender. If okay, replace sender. If not okay, repair wire or connector.
