Solution

1. Preparation

Tools Required: Socket set, torque wrench, fuel line disconnect tool, OBD-II scanner, multimeter.
Disconnect the negative battery cable to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls.

2. Access the Fuel Pump

Sub-steps:
1. Remove the rear seat cushion by pulling up on the front edge and lifting it out.
2. Remove the access panel in the floor to expose the fuel pump assembly.
3. Disconnect the electrical connector and fuel lines from the fuel pump.

3. Remove the Fuel Pump

Sub-steps:
1. Use the fuel line disconnect tool to safely detach the fuel lines without damaging them.
2. Unscrew the retaining ring that holds the fuel pump assembly in place.
3. Carefully lift the fuel pump assembly out of the tank.

4. Install the New Fuel Pump

Sub-steps:
1. Inspect the new pump and ensure it matches the old one.
2. Place the new fuel pump assembly into the tank, aligning it properly.
3. Secure it with the retaining ring, ensuring it is tightened to the manufacturer's specifications (typically around 15-20 ft-lbs).
4. Reconnect the fuel lines and the electrical connector.

5. Reassemble and Test

Sub-steps:
1. Replace the access panel and the rear seat cushion.
2. Reconnect the negative battery cable.
3. Turn the ignition key to the "ON" position (without starting the engine) to prime the fuel system and check for leaks.
4. Start the engine and monitor for proper operation and any leaks.
