Is there any procedure for diagnosing if your ECM is bad ? Also do the ECM's have to be calibrated to the VIN or VATS ?
I have a start but no run condition and I am starting to think somehow my ecm is bad. I cannot read it with HPTuners and their support is suggesting I have it re-flashed with a GM tech2 back to stock and then I would be able to communicate with it. Seems it would be more beneficial to buy another ECM then to pay someone to reflash it to a tune that will not work with the car as it sits.
