Not to discourage you guys. Bought my 21 Silverado 3.0 Dec 4, 2020. The following month had the crank no start issue. They did the inspection on the camshaft fly wheel issue. Came back good. Took the truck home. Since then it’s done it every other month. I had my ECM flashed on Nov. 17 2021 with the latest update. Still having the issue. Brought it to the dealer and they had yet another update with new fuel parameters and had my ecm reflagged again on 3/3/2022. Once again 3/5/2022 going to leave work crank no start issue has occurred again. My Silverado has been in for this issue 9 times. Towed 3 times. No idea what to do next.
