My 2017 silverado auto shuts off when I put it in drive but does not give me an error. I have waited a few hours and it just rough idles on park and turns off as soon as I put it in drive. Has anyone had this issue?
I'll guess that it's a fuel error, probably not enough pressure.
You have 2 pumps, one gets fuel from the tank to engine area where the 2nd pump takes over and applies very high pressure to the injectors.
Sorry, I don't have any testing info.
