Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working on the fuel system.

2. Inspect and Replace the Fuel Filler Cap

Sub-steps:
1. Remove the fuel filler cap and inspect the rubber gasket for cracks or deterioration.
2. If damaged, replace with a new fuel filler cap.
3. Reinstall the cap and ensure it is securely tightened.

3. Locate and Repair Fuel Leaks

Sub-steps:
1. Visually inspect fuel lines, injectors, and the fuel tank for signs of leakage or corrosion.
2. If a leak is found, replace the damaged fuel line or injector as needed.
3. Tighten any loose fittings and replace any O-rings or seals that appear worn.

4. Conduct Fuel System Pressure Test

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the "On" position without starting the engine and observe the pressure reading.
3. If pressure is below specifications, troubleshoot potential causes and replace the fuel pump if necessary.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminal.
2. Start the vehicle and check for any new fuel odors.
3. Monitor for leaks and observe if the check engine light remains illuminated.
