Locate the fuel level sensor connector, typically found near the fuel tank.
Disconnect the connector and visually inspect the wiring for any signs of damage.
If damaged, repair the wiring using appropriate automotive wire and connectors, ensuring good insulation.

3. Replace Fuel Level Sensor

If the wiring is intact, proceed to remove the fuel level sensor:
1. Remove the fuel tank access cover (if applicable).
2. Disconnect the fuel lines from the fuel pump assembly.
3. Unscrew the retaining ring securing the fuel pump assembly and carefully remove the assembly.
4. Replace the fuel level sensor attached to the assembly.
5. Reassemble the fuel pump assembly and reconnect all lines and connectors.

4. Reconnect Battery and Test

Reconnect the vehicle battery.
Turn the ignition to the "ON" position without starting the engine to allow the fuel gauge to reset.
