car repair

You need to remove the fuel pressure on the rail. Then remove the fuel rail bolts so you can pull the rail up. Some injectors will stay in the engine and some will come out with the rail. Remove the faulty injector. Replace with some light lubrication on the O rings so they will seal. Press the rail firmly down on the injectors to seat them into the intake. Install bolts in fuel rail. Turn key on a couple of times and check for leaks.
