Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Address Fuel Leak

Inspect Fuel Lines:
- Use a socket set to remove any covers obstructing access to fuel lines.
- Visually inspect all fuel lines for cracks or damage.
Repair or Replace:
- If a leak is found, replace the damaged section of the fuel line using appropriate fuel line connectors.
- Tighten all fittings securely to prevent leaks (use torque specifications as per manufacturer guidelines).

3. Replace Fuel Cap (if necessary)

If the fuel cap is damaged, replace it with a new OEM fuel cap.
Ensure the new cap clicks into place to create a proper seal.

4. Clear Codes and Test

Use the OBD-II scanner to clear any diagnostic trouble codes (DTCs) related to the fuel system.
Reconnect the battery and start the engine.
Monitor for any reoccurrence of the check engine light.
