Solution

1. Preparation

Gather tools and replacement parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Access the Fuel Sending Unit

Tools Required: Socket set, screwdrivers
Remove the rear seat or access panel to reach the fuel tank.
Unfasten any retaining bolts or screws holding the cover in place.
Carefully lift the cover to expose the fuel sending unit.

3. Inspect and Replace the Fuel Sending Unit

Disconnect the wiring harness from the fuel sending unit.
Remove the retaining ring or screws securing the sending unit and lift it out of the tank.
Inspect the float arm for proper movement and check for any physical damage.
If necessary, replace the sending unit with a new one.
Reinstall the sending unit by reversing the removal steps and ensuring a proper seal.

4. Reconnect Electrical Connections

Reconnect the wiring harness securely to the new or inspected sending unit.
Check the gauge cluster connections for corrosion or damage and clean if needed.

5. Test the System

Reconnect the battery.
Start the vehicle and observe the fuel gauge for proper function.
If the gauge still does not work, inspect the gauge itself and consider replacing it.
