    I will try and find the ID and Operating system info to see if numbers match.

    I didn't see the email though. I'll send you one.

    Can anybody tell me if there is a difference between constant power and cranking power? Or switched power and cranking power? Just wondering if at the time of the pcm swap, I missed something there.

    Still have no crank signal at OBDII port in cab.

    Have you double checked your repin work? It's really, really easy to miss something. I'd go through the pinout one more time to be sure everything is as listed on the spreadsheet. IF that checks out, as long as you have a compatible operating system such as 12212156, check your tune to ensure that "System | Vehicle Platform | Parameters" is set to GMT610 and that "System | Vehicle Platform | Vehicle Platform Options | Low Resolution Crank" is set to yes. That will enable the low res crank and you should see the signal.

    Thanks for the info. I will double check my pinout. Again. Then I'll check into the OS info to make my numbers line up.

    Here's hoping.....

    So, as it turns out, it was the computer. Got a proper computer and double checked wires and had tuner guy come and flash and install base tune. Should be all good, right? WRONG!
    Still can't get this SOB to start! It turns over like it's out of fuel, and after a few tries, it smells like it's flooded. We have checked firing order, spark (it's a little weak, kind of orange. Putting in a new coil today), fuel pressure,
    ohmed all the wires to the fuel injector block. Checked all the wires again to the computer. And I'm sure something else I have forgotten about.

    This truck won't even pop. No try whatsoever.

    Has anybody got anything that I might try??
    This truck has been down for two months already and I'm starting to lose my mind.

    Try to get your tuner to post the file that he is using.
