Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked in a well-ventilated area.

3. Repair or Replace Fuel Lines
  • Locate the fuel lines running from the fuel tank to the engine.
  • Inspect each line for cracks or leaks. If any are found:
    • Use a socket set to disconnect the lines at the fittings.
    • Replace damaged sections with new fuel line sections, ensuring they meet OEM specifications.
    • Reconnect the lines and tighten fittings to the specified torque.
4. Check and Replace Fuel Injectors
