Fuel Injector: Service Precautions

CAUTION:
^ Do not attempt to put battery voltage to the fuel injector or damage to the fuel injector will occur.
^ To prevent engine damage, do not use air tools to remove the fuel injectors. The clip that extracts the injector can dislodge and fall into the oil drain hole.
