Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the vehicle battery to prevent electrical shocks.
Allow the engine to cool completely before beginning work.

2. Inspect and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter, typically found along the fuel line.
2. Use a socket set to remove the fuel filter from its mounting.
3. Inspect the old filter for signs of clogging or contamination.
4. Install the new fuel filter, ensuring it is oriented correctly (check flow direction).
5. Secure the filter back into place and reconnect any hoses.

3. Test Fuel Pump

Sub-steps:
1. Remove the access panel to the fuel pump (if applicable).
2. Disconnect the electrical connector from the fuel pump.
3. Use a multimeter to check for voltage at the pump connector.
4. If voltage is present, replace the fuel pump; if not, trace back to the fuel pump relay and wiring.
5. Install the new pump, reconnect the wiring, and replace the access panel.

4. Evaluate Fuel Injectors

Sub-steps:
1. Remove the fuel injector connectors and unscrew the injectors from the rail.
2. Use a fuel injector tester to verify operation; replace any faulty injectors.
3. Clean injector ports and ensure they are free of debris.
4. Reinstall the injectors into the fuel rail, ensuring a secure fit.

5. Clear Error Codes

Sub-steps:
1. Reconnect the vehicle battery.
2. Use the OBD-II scanner to clear any stored error codes.
3. Perform a test drive to ensure the check engine light does not reappear.
