Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Fuel Pump Access Cover

Locate the fuel pump access cover under the rear seat or in the trunk area.
Remove any retaining screws or clips using a socket set.
Carefully lift the cover to access the fuel pump assembly.

3. Disconnect Fuel Lines and Electrical Connector

Relieve fuel system pressure by loosening the fuel filler cap.
Carefully disconnect the fuel lines from the pump using a fuel line disconnect tool.
Unplug the electrical connector from the fuel pump by pressing the release tab.

4. Remove the Fuel Pump Assembly

Unscrew the retaining ring or bolts securing the pump assembly to the fuel tank.
Carefully lift the fuel pump assembly out of the tank, taking care not to damage the fuel tank.

5. Install New Fuel Pump

Place the new fuel pump into the fuel tank, ensuring it is seated correctly.
Reinstall the retaining ring or bolts to secure the pump assembly, tightening to manufacturer specifications (typically 20-25 ft-lbs).
Reconnect the electrical connector to the new fuel pump and ensure it clicks into place.
Reattach the fuel lines, ensuring they are secure and leak-free.

6. Reassemble and Test

Replace the fuel pump access cover and secure it with screws or clips.
Reconnect the negative battery terminal.
Turn the ignition to the "on" position without starting the engine to prime the fuel system and check for leaks.
Start the engine and monitor for proper operation.
