Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, fuel pressure gauge, and smoke machine.
Ensure you are in a well-ventilated area and the vehicle is parked securely.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Inspect and Replace Fuel Filler Cap

Remove the fuel filler cap.
Inspect for cracks or damage and ensure the rubber seal is intact.
If damaged, replace with a new OEM fuel filler cap.

3. Check and Repair Fuel Lines

Visually inspect the fuel lines for any signs of wear or leaks.
If any leaks are found, replace damaged sections of the fuel line using appropriate fuel line connectors.
Ensure all connections are tight and secure.

4. Test and Repair EVAP System

Connect the smoke machine to the EVAP system via the service port.
Observe for any smoke escaping, indicating leaks in the EVAP system.
Repair any identified leaks by replacing faulty components, such as the EVAP canister or purge valve.

5. Fuel Pump Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check the fuel pressure.
If the pressure is below specifications, replace the fuel pump according to manufacturer guidelines.

6. Clean or Replace Fuel Injectors

Use a fuel injector cleaning kit to clean the injectors.
If cleaning does not resolve the issue, replace the fuel injectors as necessary.
