Solution

1. Preparation

Tools Required: Safety goggles, gloves, OBD-II scanner, flashlight, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect Fuel Lines

Locate the fuel lines running from the tank to the engine.
Visually inspect for cracks or signs of wear.
If leaks are found, replace the damaged sections of the lines.

3. Check Fuel Injector Seals

Remove the engine cover if necessary.
Inspect the fuel injectors and their seals for fuel leakage.
If leaking, replace the seals or the entire injector as needed.

4. Examine Fuel Tank

Safely lift the vehicle using jack stands.
Inspect the fuel tank for any punctures or cracks.
If damage is confirmed, replace the fuel tank.

5. Verify Fuel Cap

Inspect the fuel cap for cracks and ensure it seals properly.
Replace the fuel cap if it is damaged or does not seal.

6. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (do not start) and check the pressure reading.
If the pressure is out of spec, further diagnose the fuel pump and pressure regulator.
