    Misfire - 3rd cylinder pumping out heaps of fuel

    Need some help,

    I have a stock standard 06 GTX S/C 185.

    Its developed a misfire of late that after a few minutes generally goes away and runs well. However i took it out and the misfire remained. Brought it home, found no. 3 cylinder spark plug very wet. Other two a nice grey colour.

    A fresh set of plugs and i try again...same problem.

    I turned the ski over will all plugs out and noticed a massive amounts of fuel being pumped out of no, 3 but none of the others. There is that much fuel that it is almost raining when ii turn the motor over.

    I have stopped turning the motor over.

    Any thoughts. A faulty injector that is just pulsing way harder than it should??? Has anyone heard of this before???

    Pete

    When i say "turned the ski over" i mean turn the motor with the starter motor, just to clarify i didnt turn whole boat upside down.

    Ok, pulled the fuel rail and injectors out. As soon as I plug the key in, the no. 3 injector is pumping fuel. The others are not.....why????

    Are you positive it is fuel being pumped out? I'd remove the injector rail and see what is happening with the injectors.

    Yep its fuel, pulled the rail and injectors out and you can see the no. 3 injector squirting heaps of fuel. Swapped the no.3, injector electrical plug onto the no. 2 injector and guess what...now the no. 2 fuel injector is running when i plug the key in. So for some reason the no. 3 fuel injector connection is giving a signal but i don't know why.

    Your injector is bad,buy a new one and you wont have a problem.
    I had the same experience, installed new injector and the problem is solved.

    When you put the dess key on ,the system automatically sets pressure on the fuelline,since you have a bad injector it will start spraying fuel in your cylinder.

    Thats what i thought initially but when i put the no 3 injector connection on the no 2 injector, the no 2 injector starts spraying fuel and the no 3 injector is fine...

    Hoping that the injector connection is grounding out somewhere and its not a bad ecu sending a faulty signal.
