Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel filler cap and using the fuel pump relay to start the engine until it stalls.

2. Access the Fuel Pump

Remove the rear seat cushion by pulling up on the front edge to release the clips.
Remove the access cover for the fuel pump located under the rear seat.
Disconnect the electrical connector from the fuel pump module.

3. Remove the Fuel Pump Module

Carefully disconnect the fuel lines from the pump module using a fuel line disconnect tool if necessary.
Unscrew the retaining ring securing the fuel pump module to the tank. Use a mallet and a drift punch if it's tight.
Lift out the fuel pump module from the tank, taking care not to damage the O-ring seal.

4. Install New Fuel Pump

Install the new fuel pump into the module, ensuring it is properly seated.
Replace the O-ring seal if provided with the new pump.
Reinstall the fuel pump module into the tank, securing it with the retaining ring.
Reconnect the fuel lines and electrical connector.

5. Reassemble and Test

Reinstall the access cover and rear seat cushion.
Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine to prime the fuel system, then check for leaks.
Start the engine and monitor for proper operation.
