Injector Fuel Leakage

  1. On non-turbo models, remove dynamic chamber. See Figure . On all models, loosen delivery pipe attaching bolts. Remove delivery pipe. Using wire, secure injectors tightly onto delivery pipe.
    CAUTION: Ensure injectors are securely tied to delivery pipe. If not properly secured, fuel may spray from loose connections.
  2. Install jumper wire between 2 terminals of fuel pump test circuit connector. See Figure . Turn ignition on. Check that no fuel leakage exists at injectors. After 5 minutes only a slight amount of fuel leakage is acceptable.
