    2002 155 GTX injector issue?

    I am working on buddies ski. Seems an injector is stuck open. Runs like shit, pull plugs & one jug (I think front will have to double check been a while since I played with it) has fuel in it. Like injector is stuck open. All 3 have spark, but that one loads/ dumps fuel.

    throughs a code 12v ground fault injector 3.

    open to ideas & fixes. Replaced all 3 injectors.. same issue

    Can I omh out it check wiring for an issue?

    known problems?

    Swap the suspect fuel injector with another cylinder, see if the problem moves with the injector?

    If you have replaced all three injectors and it's still dumping fuel in one cylinder the ECU is likely bad.

    Is there a way to check the ECU?

    also being told his battery tender cable was shorted/ burnt so maybe that took out the ecu?

    That's probably going to total out the ski. ECUs are difficult to find, there is one on ebay for $1k. There are updated ecus that you can use from other 155's, the newest one requires you to remove the DESS amp or it will immediately ruin the new ECU. Have you looked at the ECU connectors? If water especially salt water sits in that connector it will corrode the pins on the ECU and connector.
