  • If leaking injectors are identified:
    1. Relieve fuel system pressure as described above.
    2. Disconnect the electrical connectors from the fuel injectors.
    3. Remove the fuel rail by unbolting it from the intake manifold.
    4. Carefully remove the old injectors from the rail and replace them with new ones, ensuring to lubricate the O-rings with clean engine oil.
    5. Reinstall the fuel rail, ensuring all bolts are torqued to specifications.

Step 4: Repair or Replace EVAP Components

  • Tools Required: Ratchet set, smoke machine.
  • If leaks are found in the EVAP system:
    1. Identify the faulty component (e.g., purge valve, canister).
    2. Remove and replace the damaged component as per manufacturer instructions.
    3. Re-run the smoke test to ensure all leaks are repaired.
Final Steps
  1. Test Drive: After repairs, conduct a test drive to ensure no fuel odor is present and that the vehicle operates normally.
  2. Clear Fault Codes: If applicable, use an OBD-II scanner to clear any fault codes that may have been triggered.
  3. Monitor: Keep an eye on the area for any signs of leaks or odors over the next few days.
