Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set, screwdriver set, safety glasses, and gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Remove the Fuel Pump

Disconnect the battery to prevent any electrical shorts.
Relieve fuel system pressure: Locate the fuel pump fuse and remove it; then start the engine until it stalls. This will relieve pressure in the fuel lines.
Access the fuel pump: Depending on the model year, remove the rear seat or access panel in the trunk to reach the fuel pump assembly.
Disconnect electrical connectors and fuel lines from the pump.

3. Inspect and Replace the Fuel Pump

Remove the fuel pump assembly: Unscrew the retaining ring and carefully lift the pump assembly out of the tank.
Inspect the old fuel pump for any visible signs of wear or damage.
Install the new fuel pump: Place the new pump in the assembly, ensuring proper orientation. Replace the retaining ring and reconnect the fuel lines and electrical connectors.
Reinstall the access panel or seat.

4. Reconnect and Test

Reconnect the battery.
Replace the fuel pump fuse and turn the ignition to the ON position (without starting) to prime the pump.
Check for leaks around the fuel lines and pump assembly.
Start the engine and monitor for smooth operation.
