Ran flow chart a-3 by the book!! That is why I replaced the module, all pins tested good end to end!! Also ran crank no start chart, it stated to replace ecm, I happen to be an ase certified gm technician, I do not hang parts!!!! I went with the test results from the manual!! Hears a good one for ya, let car sit all last week, pushed it back in shop battery was low from sittin in the cold, charged battery while I was doin other things. When I went to the car hit the key and started right up.
