Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety glasses and gloves.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box.
Start the engine and then remove the fuse, causing the engine to stall.
Turn off the ignition and wait for 10 minutes to allow pressure to dissipate.

3. Remove the Fuel Pump

Tools Required: Fuel line disconnect tool, socket set, torque wrench.
Disconnect the negative battery terminal to prevent electrical shorts.
Access the fuel pump by removing the rear seat or trunk cover (depending on the model).
Unscrew the fuel pump access panel and disconnect the electrical connector.
Carefully disconnect the fuel lines using the fuel line disconnect tool.
Remove the retaining ring securing the fuel pump and take out the pump assembly.

4. Inspect and Replace

Inspect the old fuel pump for any signs of damage or wear.
Check the fuel filter within the pump assembly for clogging.
Parts Required: New fuel pump, new fuel filter (if applicable).
Install the new fuel pump by reversing the removal steps, ensuring all connections are secure.

5. Reassemble and Test

Reconnect the fuel pump access panel and reinstall the rear seat or trunk cover.
Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position to prime the fuel system and check for leaks.
Start the vehicle and monitor for normal operation.
