working on a 03 lb7 auto, have the fuses pull, truck took a single file tune, then when switching to a dsp5 full os reflsash it would not reboot the ecm, and the dash just blinks and clicking under the hood. Swapped to another ecm and bought another liecense and flashed to tucks stock OS and truck ran fine, then went to do a another dsp5 flash and truck did the same thing at the end, would not reboot at the end of the flash progress, any idea's what is going wrong or ideas how to retrive the ecm to work so I dont have to get another ecm and another liscense??
