      I need help i have a 2019 silverado 2500hd with the 6.0 gas bought it with no key. Had a locksmith come out and he make a key it was late and cold he was not able to get the key programmed at the time. So i got in the truck after he left and tried the 30 minute key reset. Well it fired up and ran drove it around the block and cut it off and now it wont start back up. The key guy came back out and got the key programmed and still the truck will not start backup no theft light is on. Checked for fire and fuel pressure it has both but it will not start backup i cant firgure out why it will not start. It ran and drove fine until i cut it off any ideals ? I think it has something to do with the theft system??
