  • 2002 virage txi 1200 bad injector ??

    I bought this ski last week and need some advice.
    it had a no start and i was not getting fuel pressure. found the pump bad so I replaced it with OE pump. now i have good fuel pressure when I ground the brown wire.
    spark is good and cranking voltage is over 10.5. engine cranks fast. still no start unless i add some fuel into each intake. This lead me to test voltage to injectors. when cranking i only had 7-8 volts at the white with red stripe wire. I tested the stator and getting the correct ohms on everything and correct voltage while cranking. I tried unplugging all injectors and got 28 volts at crank. started plugging in injectors one at a time and find with the middle injector plugged in voltage drops to 8 volts but when unplugged i see 28 volts. Do i have a bad injector or bad computer ?? I have been doing my reading and cant figure out what I need to replace and try.
    Since the computers have so many problems i figure it is the problem but want to be sure before sending it out for repair.

    Welcome to GreenHulk !

    Is there a big difference in resistance between the three injectors ? IIRC the resistence is pretty low-and injectors are pretty durable,but worth closer inspection.

    The voltage test does need to have all 3 injectors plugged in to be accurate, but if one was shorted it would bring down the average. An Ohm test should show if it is shorted.

      That is most likely an EMM issue. Lakeside Tech can help you with that.
