Solution

1. Preparation

Gather tools: socket set, wrench set, OBD-II scanner, fuel pressure gauge, multimeter.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Repair Fuel Lines

Tools Required: Socket set, wrench set.
Sub-steps:
1. Locate and inspect the fuel lines running from the fuel tank to the engine.
2. Replace any damaged or cracked fuel lines with new, OEM-approved lines.
3. Secure all connections with appropriate clamps and ensure there are no kinks in the lines.

3. Check Fuel Injectors

Tools Required: Socket set, fuel pressure gauge.
Sub-steps:
1. Remove the engine cover (if necessary) to access the fuel injectors.
2. Inspect each injector for signs of fuel leakage.
3. If a leak is found, replace the affected injector using a new OEM part, ensuring proper seating and connection.

4. Examine Fuel Tank and Pump

Tools Required: Socket set, wrench set.
Sub-steps:
1. Safely raise the vehicle and support it on jack stands.
2. Inspect the fuel tank for corrosion or damage, especially around the seams.
3. If a leak is detected, the fuel tank may need replacement.
4. Check the fuel pump assembly for proper sealing and functionality; replace if necessary.

5. Inspect EVAP System

Tools Required: Multimeter.
