Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, multimeter, screwdriver, and safety glasses.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent electrical shock during repairs.

2. Inspect and Replace Fuel Cap

Remove the fuel cap and check for cracks or damage.
If damaged, replace with a new OEM fuel cap.
Reattach the fuel cap securely and ensure it clicks into place.

3. Check and Replace Fuel Pump (if necessary)

Locate the fuel pump access panel (usually under the rear seat or trunk).
Remove the access panel and disconnect the fuel pump electrical connector.
Use the fuel pressure gauge to check if the fuel pump is delivering adequate pressure (typically 35-50 psi).
If pressure is low, remove the fuel pump assembly, replacing it with a new unit if faulty.
Reconnect the electrical connector and secure the access panel.

4. Inspect EVAP System

Locate the EVAP canister and purge valve, usually found near the fuel tank.
Check for cracks or blockages in the hoses connected to the EVAP system.
If the purge valve is faulty (stuck open or closed), replace it with a new unit.
Clear any debris or build-up in the charcoal canister.

5. Reconnect Battery and Test

Reconnect the battery terminal.
Start the engine to check for improvement and ensure the problem is resolved.
