    Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.

    1.Disconnect the negative battery cable, for safety purposes.
    2.Remove the fuel rail.
    3.To remove the fuel injector from the fuel rail, remove the fuel injector retainer screws and press the fuel injector out from the fuel rail. Discard the O-rings.
