Fuel Gauge Always Indicates Empty
- If diagnostic system check has been performed, go to next step. If diagnostic system check has not been performed, perform INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
- Turn ignition off. Ensure fuel level is at least 3/16 full. Turn ignition on and observe fuel gauge. If fuel gauge does not indicate about where fuel level actually is, go to next step. If fuel gauge indicates about where fuel level actually is, problem may be intermittent. Try to recreate fault by wiggling wiring and connectors. Check for faulty connections at all connectors that may be causing intermittent condition. See WIRING DIAGRAMS .
- Connect scan tool to Data Link Connector (DLC). Using scan tool, perform fuel gauge sweep test. If fuel gauge does not sweep from empty, to full and then return to empty, go to next step. If fuel gauge sweeps from empty, to full and then returns to empty, perform on-board diagnostic system check. See ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
- Replace instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Check system operation.
