Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorting.

2. Remove Fuel Sender Unit

Tools Required: Socket set, screwdrivers.
Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
2. Lift the rear seat cushion to access the fuel sender access panel.
3. Remove the access panel and disconnect the wiring harness from the fuel sender.
4. Unscrew the fuel sender unit and carefully remove it from the tank.

3. Inspect and Replace Fuel Sender Unit

Tools Required: Multimeter, replacement fuel sender unit (if faulty).
Sub-steps:
1. Use a multimeter to test the resistance of the fuel sender unit. A range of 0-90 ohms is typical when the tank is full to empty.
2. If readings are outside this range, replace the fuel sender unit with a new one.
3. Install the new sender by reversing the removal steps, ensuring all connections are secure.

4. Reassemble and Test

Sub-steps:
1. Reconnect the wiring harness and secure the access panel.
2. Reconnect the negative battery terminal.
3. Replace the fuel pump fuse and turn the ignition on, allowing the fuel system to pressurize before starting the engine.
