SOURCE: How do you replace the O-rings on the fuel injector?

to relieve pressure, there may be a purge valve somewhere on the injector rail, or if not, simply loosen one of the injectors slowly until pressure bleeds off of the system. then replace the o-rings carefully so as not to tear them.

Yes it is in the fuel tank. You either have to remove the fuel tank or take off (raise) the bed to get to it. Many people tell me it is just as easy to raise the bed up as it is to drop the fuel tank out of it, especially if the tank has very much gas in it. Please rate my answer so I am rewarded points for it.

sound like the o rings are worn out on fuel rail when you pull the rail out slightly you are pinching the bad O ring making a seal car is starting. I would replace all O rings check fuel injector seals too, any and all vacuum lines and the seal on the fuel regulator especially if it is connected to the fuel rail.
also check and see if you are moving a wire connections when moving the fuel rail possible loose connection.

Gas is leaking from my fuel rail (phlegm) on my number 5 fuel injector on my 1994 camaro

  • Park the Camaro on a flat, level surface and set the parking brake. Open the hood and secure it in place with the hood prop. Disconnect the negative battery cable.
  • Open the gas tank to relieve pressure on the fuel lines.
  • Remove the sight shield from the fuel injector with a socket wrench. Loosen the screws on the hose clamps and disconnect the fuel lines connected to the injectors. Keep a rag handy to catch any fuel that leaks.
  • Disconnect the vacuum hose and ignition coil wire, then unplug the electrical connectors. Remove the fuel injector mounting bolts, undo the retaining clips and remove the fuel injectors.
  • Put a thin coat of engine oil on the new fuel injector's O-ring. Place the O-ring in position, install the new fuel injectors and secure the retaining clips. Install the mounting bolts with a torque wrench set at seven pounds.
  • Plug the electrical connectors back into the fuel injectors. Reconnect the vacuum hose and ignition coil wire. Connect the fuel lines and tighten the hose clamps with a screwdriver to secure them in place. Bolt the sight shield in place with a socket wrench.
  • Place the gas cap back on. Reconnect the negative battery cable

    How do i remove the fuel injectors on a 1994 camaro 3.4 v6 im trying to replace the intake manifold gasket and cant get the injectors out of the fuel rail

    You can generally remove all injectors with the fuel rail as a unit. Just unplug them from the wiring harness and pull up the fuel rail. The injectors are just pushed in with o-rings.

    how often do you idle this blazer. if you idle alot this this adequetly lubricate the cylinder walls and what happens is "fuel wash", which then progressively wear the cylinders,rings,and piston ring lands and grooves. you may also have a throttle body/injector problem causing over fueling. any sign of smoke?

    1994 chevy fuel problem

    The last pieces in the chain are the fuel regulator and the injectors. The regulator is inside the throttle body, but it sounds that maybe the injectors are not firing. For nothing else, check out the connections to the injectors. Possibly they are clogged. Try a few treatments of injector cleaner.

    How to replace the fuel injectors on a 2002 Tahoe?

    To Install:
    1. Lubricate the NEW fuel injector O-rings with clean engine oil.
    2. Install the O-rings on the fuel injector.
    3. Install a NEW retainer clip on the fuel injector.
    4. Install the fuel injector in the injector socket with the electrical connector facing outward. The retainer clip locks onto a flange at the fuel rail injector socket.
    5. Install the fuel rail.
    NOTE: Use care in removing the fuel injectors in order to prevent damage to the electrical connector pins on the injector and to prevent damage to the nozzle. Service the fuel injector as a complete assembly only. The fuel injector is an electrical component. DO NOT immerse the fuel injector in any type of cleaner.

    are you sure that the fuel injectors were clean when you replaced the o-ring or maybe there is still a piece of o-ring left inside the fuel injector port if this still does not work then replace o-ring with two rings a smaller o-ring and a larger one
