Turn off the fuel system pressure, disconnect the battery negative cable, and pull off the engine cover. Unplug the fuel injector wires, then take off the tube connecting the front and back fuel rails before putting it next to you. Take off four bolts that hold the fuel rails in place, and pull apart each fuel rail with its three injectors. Press the fuel rail gently forward, sideways, then back again until you can lift it off. First, take out the retainer of the fuel rail. Pull the injector in a straight line carefully until it leaves the fuel rail. Take off and throw away the upper and lower injector O-rings, then do this for each injector. For best results, take all the injectors out of the fuel rail and switch all O-rings regardless of which one needed work. By rubbing oil onto both ends of each injector, put the new O-ring pieces at the top and bottom into their proper positions. Oil the outside of each O-ring carefully, then push each fuel injector into its right position on the fuel rail. Put the injectors back on the intake manifold by hand, making sure all fuel rail mounting bolts stay tight. Afterwards, we undo everything in the same steps as installing it. Replace everything by attaching the cable to the negative battery terminal. Turning the ignition to ON but not starting the engine puts fuel pressure into fuel pipes and the fuel rail for two seconds. Rephrase the following sentence. Normalize verbalization where possible.
