    Dead`Injector or EMM

    Have a 2002 STX DI 1100 that is DOA. I am wondering if a fuel injector fails will it shut down the engine, maybe as a safety precaution. Long story short the ski cranks over but has no spark. If i disconnect the fuel injector on the forward cylinder I then have spark on all 3 cyclinders and it will run on the remaining 2 cylinder.
    Any chance it is a single injector and not the entire EMM?
    Any experience on this would be greatly appreciated

    Does this no spark condition continue to happen if you unplug any other cylinders and leave the forward connected?

    If the forward injector is plugged in it has no spark on any cylinder. Once`it is unplugged all cylinders have spark and it will run (less the forward cylinder because the injector is unplugged)

    After looking at your post. If i leave the front cylinder plugged in and remove the others it still has no spark.

    Plugging in the injector seems to shut down the system. Thats why I wonder if it is a fail safe on a possible bad injector????
