Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and safely supported.

2. Inspect and Replace Fuel Filler Cap

Check the fuel filler cap for cracks or damage.
If damaged, replace with a new OEM or equivalent fuel filler cap.
Tighten the new cap until it clicks securely.

3. Check and Test the EVAP System

Locate the EVAP purge valve, usually found near the intake manifold.
Disconnect the electrical connector and vacuum line.
Use a multimeter to test the valve for continuity.
If faulty, replace the EVAP purge valve.

4. Fuel Pump Inspection

Access the fuel pump by removing the rear seat or trunk panel.
Disconnect the electrical connector and fuel lines (use safety glasses).
Test the fuel pump with a fuel pressure gauge; ensure it meets manufacturer specifications.
If the pressure is low, replace the fuel pump.

5. Inspect Fuel Injectors

Remove the intake manifold if necessary to access the fuel injectors.
Check for clogs or leaks in the injectors.
Clean or replace any faulty fuel injectors.
