Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working.
Gather an OBD-II scanner, fuel pressure gauge, multimeter, socket set, and safety glasses.

2. Inspect and Replace Fuel Pump (if necessary)

Remove the rear seat or access panel to expose the fuel pump assembly.
Disconnect the electrical connector and fuel lines from the pump.
Remove the fuel pump retaining ring using a hammer and a screwdriver or a specialized tool.
Carefully lift the fuel pump assembly from the tank.
Inspect the pump for any signs of damage or wear.
Replace the fuel pump with a new OEM or quality aftermarket unit.
Reassemble the fuel pump assembly, ensuring all connections are secure.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter, which may be integrated with the fuel pump assembly.
Disconnect the fuel lines from the filter, taking care to catch any spilled fuel.
Remove the filter from its mounting bracket.
Install the new fuel filter, ensuring correct orientation for fuel flow.
Reconnect the fuel lines securely.

4. Test Fuel System

Reconnect the battery and turn the ignition to the "ON" position without starting the engine to prime the fuel system.
Use the fuel pressure gauge to verify that the pressure meets the specifications listed in the vehicle's repair manual.
If pressure is within specs, start the engine and monitor for leaks.
