Solution

1. Preparation

Tools Required: Safety glasses, gloves, OBD-II scanner, fuel pressure gauge, multimeter, socket set.
Disconnect the negative battery terminal to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Inspect and Replace Fuel Filter

Locate the fuel filter; it may be integrated with the fuel pump assembly in some models.
Remove the fuel filter using a socket set.
Replace with a new fuel filter that meets OEM specifications.
Reconnect the fuel lines ensuring they are secure.

3. Test and Replace Fuel Pump (if necessary)

Access the fuel pump by removing the rear seat or accessing the trunk as per manufacturer instructions.
Disconnect the fuel pump electrical connector.
Use a multimeter to check for proper voltage while cranking the engine.
If the voltage is correct but the pump is not working, replace the fuel pump with a new unit.
Reassemble all components securely after replacement.

4. Clean or Replace Fuel Injectors

Remove the fuel rail by unscrewing the retaining bolts and gently pulling it away from the intake manifold.
Carefully remove the injectors from the rail; take note of their orientation.
Clean the injectors using a fuel injector cleaning kit or replace them if they are clogged.
Reinstall the injectors and fuel rail, ensuring proper sealing.

5. Reconnect and Test System

Reconnect the fuel pump relay and negative battery terminal.
Start the engine and monitor for any leaks around the fuel system.
Check for any error codes again to ensure the issue is resolved.
