Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Fuel Lines

Remove any covers or shields that may obstruct access to fuel lines.
Visually inspect all fuel lines for cracks, corrosion, or loose connections.
Use a flashlight to inspect hard-to-see areas.
Replace any damaged fuel lines with OEM parts.

3. Check Fuel Injectors

Remove the engine cover if necessary to access the fuel rail.
Disconnect the electrical connectors from the fuel injectors.
Use a fuel pressure gauge to check the injector operation by monitoring fuel flow during cranking.
Replace any defective fuel injectors.

4. Inspect the EVAP System

Locate the EVAP canister and purge valve.
Check for any cracks or leaks in the hoses connected to the canister.
Test the purge valve operation by applying power and ensuring it opens and closes properly.
Replace any faulty components in the EVAP system.

5. Reassemble and Test

Reinstall any components removed during inspection and repair.
Reconnect the battery.
Start the engine and check for any gasoline odors or leaks.
