Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Screwdriver set

2. Remove Fuel Pump Assembly

Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the battery.
Remove the rear seat (if applicable) or access panel to reach the fuel pump assembly.
Disconnect the electrical connector from the fuel pump.
Remove any retaining screws or bolts securing the fuel pump assembly and carefully take it out of the tank.

3. Inspect and Replace Fuel Sender Unit

Examine the fuel sender unit for any visible damage or corrosion.
Use a multimeter to test the resistance of the fuel level sender. It should change as the float moves.
If faulty, replace the fuel sender unit:
- Remove the float arm and sender from the fuel pump assembly.
- Install the new sender unit and ensure it is properly aligned.
- Reattach the float arm securely.

4. Reinstall Fuel Pump Assembly

Carefully place the fuel pump assembly back into the tank.
Secure it with the retaining screws or bolts using the torque specifications provided in the service manual.
Reconnect the electrical connector to the fuel pump.
Reinstall the access panel or rear seat.

5. Reconnect Battery and Test

Reconnect the battery terminal.
Reinstall the fuel pump fuse.
Turn the ignition ON (without starting the engine) to prime the fuel system and check for leaks.
Start the engine and observe the fuel gauge functionality.
