Solution

1. Preparation

Tools Required: Safety glasses, gloves, OBD-II scanner, fuel pressure gauge, socket set, multimeter, torque wrench.
Disconnect the negative battery terminal to prevent electrical shock.

2. Access the Fuel Pump

Remove the rear seats or access panel in the trunk to reach the fuel pump assembly.
Disconnect any electrical connectors and fuel lines leading to the pump. Use a fuel line disconnect tool if necessary.
Carefully unbolt the fuel pump assembly and lift it out of the fuel tank.

3. Inspect and Test the Fuel Pump

Check the fuel pump for signs of wear or damage. Replace if necessary.
Use a multimeter to check the fuel pump motor's resistance. The resistance should be within manufacturer specifications.
If the pump is faulty, proceed with replacement.

4. Install New Fuel Pump

Place the new fuel pump in the assembly and secure it.
Reconnect the electrical connectors and fuel lines. Ensure all connections are tight.
Reinstall the fuel pump assembly back into the tank and secure it with bolts.

5. Final Steps

Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position a few times to prime the fuel system without starting the engine.
Check for leaks around the fuel lines and connections.
