    Can you copy the log text that is printed during flashing and paste it here...

    (you may have to go into options and disable the 15 second countdown timer)

    (( you would still have to wait 15 seconds after a flash ))

    Try flashing again...

    Make sure nothing interrupts the bus or power (i.e. no dome light, no radio, no On-Star).

    The key must be in the On position to reflash, I am sure there is one 12V power feed to the ECM that is not present unless it is in the On pos. Was that the problem?
