Fuel Gauge Circuit Test

Remove fuel/temperature/voltmeter gauge (L body), fuel/temperature gauge assembly (C and Y bodies) or fuel gauge (all others) from instrument cluster. Check for continuity in wire between fuel tank sending unit and fuel level input pin. See Fig 1 through Fig 5 . Repair wiring if continuity does not exist.
With ignition on, check for battery voltage across the fuel gauge (B+) pin and fuel gauge ground pin. See Fig 1 through Fig 5 . If no voltage exists, check wiring for damage and power supply for fuel gauge (B+) pin.
