Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent any electrical sparks during the repair.
Wear safety goggles and gloves.

2. Inspect Fuel Lines

Locate the fuel lines running from the fuel tank to the engine.
Use a flashlight to examine the lines for cracks or signs of wear.
If leaks are found, proceed to replace the damaged sections.

3. Check Fuel Injectors

Remove the engine cover if applicable (using a socket set).
Inspect each fuel injector for fuel leakage.
If leakage is present, remove the faulty injector using a wrench and replace it with a new one. Ensure it is properly seated.

4. Fuel Cap Inspection

Remove the fuel cap and inspect the rubber gasket for wear.
If the gasket is damaged or the cap does not seal properly, replace the fuel cap.

5. Fuel Pressure Test

Attach a fuel pressure gauge to the fuel rail test port.
Start the engine and observe the fuel pressure reading (should be within manufacturer specifications).
If the pressure is low, check the fuel pump and replace if necessary.
