Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Address Fault Code

Use the OBD-II scanner to retrieve the error codes.
Document the codes and clear them from the system.
If codes reappear after clearing, focus on diagnosing the indicated components.

3. Inspect and Replace Faulty Components

Ignition System:
- Remove the engine cover if applicable.
- Disconnect the ignition coils and inspect for wear or damage; replace if needed.
- Check spark plugs for fouling or wear; replace with OEM specifications if necessary.
Fuel System:
- Check the fuel pump operation by listening for the pump's sound when turning the ignition to the "ON" position.
- Inspect the fuel filter for blockage; replace if there is significant resistance.
- Perform a fuel pressure test using a fuel pressure gauge to ensure proper operation.

4. Reassemble and Reconnect

Reinstall any components removed during the inspection.
Reconnect the battery terminals securely.
Ensure all tools and loose parts are cleared from the engine bay.
