    well now i just got a e-mail from a kid who says hes runnin his swap without a bcm? could somone put a meter on there injector feed (theres six of them not the main feed) and tell me wat the voltage is. i think thats were my problem could be coming from. i only had two volt cranking it so that just seemed low to me.

      2 volts cranking that could be your problem. is that 2 volts on the injector feed or the whole car feed.
      do you have a volt gauge inside the car. whats the gauge at when your cranking.

        I'm just busting your stones Jon. I don't go around saying OBDI FTW, just had to say it this one time since OBDII security crap was giving you all a hard time. hehe

        If it's 2 volts across the injector connector that could be because it's pulsing... 2 volts at the hot side (I think the PCM fires the injectors by grounding them) would be a problem.

          Until the day you give me something that you can do with OBDI that is not available with OBDII and is a extremely viable and necessity to performance then maybe I'll stop backing it so much.

            i think my wrong terms might be messin things up. the "injector feed" is sending twelve volts. the outputs i think they would be called ( theres one for each injector) gets 2 volts coming from the ecm wen i crank the motor over. sorry for any confusion if there was any. im stumped ill check the ecm ground. i didnt know the ecm grounds the injectors thats very helpful. thanx

              go over the grounds all around the engine too.

              im willing to bet though if Jon re-flashed the bin back so the VTD isnt disabled it might work.
