    Gersh Dernit!!



    It only fixed it for a few months! It was not the fuel pressure regulator (from what I can tell). The missing problem and Check Engine Light came back a couple days ago. I can remedy it by twisting the #5 fuel injector a few degrees, either direction. It fixes it for a few days then comes back. When it fixes it, it has more power and runs smoother than it ever has since I owned it!.

    **Anita, you mentioned that my exhaust has a strange sound to it when revved.... this is the problem!

    Two possibilities:

    -Carmax replaced the wire that goes to the injector coupler. Bad repair? (I can move the wire and the problem happens as well.)
    - Injector is failing (least likely, in my mind)

    ***Anyone have a fuel injector CONNECTOR with wire (as long as possible) laying around?
    Thanks!

    New ones from Merlin are $110 plus o-rings, aftermarket (no one has listed but they do for the same engine in a Trooper/Rodeo) are $79 special order here in TX. Misfires can also be caused by low octane fue, lean conditions caused by vacuum leaks, or carbon build up on the head/valves that causes the engine to need higher octane fuel to avoid misfire/pinging.

    Connector?

    Thanks Tone,
    Do you happen to show a listing or part number for the electrical connector for the fuel injector? (with wire?)

    I want to try that before I replace the injector.
    Thanks for your help!

    Bad news - if that is broken/damaged the only way to get just the Isuzu part is from a junk yard or to buy a big, expensive harness from Isuzu...

    why not try switching 2 of the injectors around? this will tell you for sure if it is the plug or the injector.i think the connector is a standard connector used for injectors.i will try to look tomorrow and see if they are the same as the ones used on boats.if they are i may be able to get you a connector. also did you try cleaning the connection ? maybe some corrosion causing a bad connection? shawn

    That's a good idea. I just hate to take the thing apart more than once... but I've done it once, might as well...

    thanks for the help! I'll let you know what I find.
