Solution

1. Preparation

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

2. Inspect Fuel Lines

Sub-steps:
1. Locate the fuel lines running from the fuel tank to the engine.
2. Visually inspect the lines for any signs of cracks, wear, or loose connections.
3. If any leaks are found, replace the damaged section of the fuel line.

3. Check Fuel Injectors

Sub-steps:
1. Remove the engine cover if necessary to access the fuel injectors.
2. Inspect each injector for fuel leaks while the engine is running (exercise caution).
3. If an injector is leaking, replace it with a new one.

4. Inspect and Test EVAP System

Sub-steps:
1. Locate the EVAP canister and check for any visible cracks or damage.
2. Disconnect the hoses connected to the EVAP canister and inspect for blockages.
3. Use a smoke machine to test for leaks in the EVAP system.

5. Replace Damaged Components

Sub-steps:
1. If any damaged components are found during inspections (fuel lines, injectors, or EVAP parts), replace them with OEM or quality aftermarket parts.
2. Ensure all connections are tight and secure.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and observe for any leaks or fuel smells.
Conduct a test drive to ensure the issue is resolved.
