- Safety goggles and gloves
Ensure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent electrical shorts.

2. Inspect Fuel Lines

Sub-steps:
1. Visually examine all fuel lines for cracks, corrosion, or loose connections.
2. Tighten any loose fittings and replace damaged lines as necessary.

3. Check Fuel Tank

Sub-steps:
1. Inspect the fuel tank for cracks or damage.
2. If a crack is found, the tank will need to be replaced.
3. Ensure the fuel tank cap is tightly secured and not damaged.

4. Test Fuel System Sensor

Sub-steps:
1. Use a multimeter to measure the resistance of the fuel system sensor.
2. Compare readings with manufacturer specifications; replace the sensor if it is out of range.

5. Inspect Fuel Injectors

Sub-steps:
1. Remove the engine cover to access the fuel injectors.
2. Inspect each injector for signs of leaking (wetness or fuel residue).
3. Replace any faulty injectors as needed.

6. EVAP System Check

Sub-steps:
1. Locate the EVAP canister and inspect for damage or blockages.
2. Perform a smoke test to identify any leaks in the EVAP system.
3. Repair or replace components as necessary.
