Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Test the Fuel Sending Unit

Sub-steps:
1. Remove the rear seat or access panel to locate the fuel sending unit.
2. Disconnect the electrical connector from the sending unit.
3. Use a multimeter to check the resistance of the sending unit; it should vary with the fuel level.
4. If resistance is not within specifications, replace the sending unit.

3. Check the Fuel Gauge Circuit

Sub-steps:
1. Inspect the wiring from the fuel sending unit to the gauge for any frays or disconnections.
2. Use a multimeter to measure voltage at the gauge terminal while the ignition is on.
3. If no voltage is detected, trace the circuit to find the break or short.
4. Repair or replace damaged wiring as necessary.

4. Replace the Fuel Gauge Cluster (if needed)

Sub-steps:
1. Remove the dashboard panel carefully to access the instrument cluster.
2. Unscrew and detach the fuel gauge cluster from the dashboard.
3. Install a new fuel gauge cluster, ensuring all connectors are secure.
4. Reassemble the dashboard panel.
