    Did the flash go to completion...?

    Was it a cal only flash or a full flash...?

    When flashing was complete, did you turn the ignition key to off and wait at least 15 seconds...?

    Are you certain that you flashed the correct file...?

    What vehicle is it...?

    it said it completed, and it was a calibration only flash, i have an 08 lmm, and i think maybe one of the ecm selector;s was set to an lbz but not sure. it just turns over and doesnt fire

    Did you check if any DTC's are set to maybe help narrow down what the issue might be?
    Did it take the stock tune ok?
    If still no go, maybe something has been messed up in the theft part of the ECM. Try setting G0301 to Disable and G0308 to None, both parameters are located in the System > VATS section. Then flash that in and see if it starts.

    Cheers,

    ok i'll try that, also when it reflashes it doesnt reboot like it normally does, i might have had a file set for an LBZ and i didnt know it, would that effect it?

    Open the tuning tool and select "Read PCM Calibrations"...When that process is over, try reflashing your stock tune using normal procedures...
