Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to prevent any electrical issues.
2. Inspect and Replace Fuel Lines
  • Sub-steps:
    1. Locate the fuel lines under the vehicle and visually inspect for cracks or fuel residue.
    2. If damaged, relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
    3. Disconnect the fuel lines using a fuel line removal tool.
    4. Replace the damaged fuel lines with new OEM or equivalent parts.
    5. Reconnect the fuel lines securely and ensure all clamps are tightened.
3. Check and Replace Fuel Injectors
  • Sub-steps:
    1. Remove the engine cover if necessary to access the fuel injectors.
    2. Inspect each injector for signs of fuel leakage at the connections.
    3. If an injector is leaking, disconnect the electrical connector and remove the retaining bolts.
    4. Replace the faulty injector with a new one and reconnect all connections.
    5. Reassemble the engine cover if removed.
4. Fuel Tank Inspection and Repair
  • Sub-steps:
    1. Safely lift the vehicle using jack stands.
    2. Inspect the fuel tank for any visible cracks or damage.
