Injector Fuel Leakage

  1. Remove dynamic chamber and loosen delivery pipe attaching bolts. Remove delivery pipe. Using mechanic's wire, tie injectors tightly onto delivery pipe.
    CAUTION: Ensure that injectors are tied tightly to fuel delivery pipe. Failure to do so will cause fuel to spray out of loose connections and cause fire hazard.
  2. Connect a jumper between 2 terminals of fuel pump test circuit connector. See Figure . Turn ignition on. With system pressurized, there should be no fuel leakage at injectors.
  3. Leave system pressurized for 5 minutes and note any leakage. Only a very slight amount of fuel leakage is acceptable.
