Tried a few different files and same issue until truck ended up just not cranking at all. Found out the truck was flashed with hp originally so ended up finding the original tune file as well so I flashed that file in and having the same issue no crank no start.... no codes anywhere I can see with alphaobd. Never fails a flash and can communicate with the ecm completely lost with this....
