This is the second time I've heard of this with the 2020 and cam swaps. Dave Weber at MMX might be able to help with that. It was his 2020 Ram it happened on. It took them a few weeks to figure it out. Give him a call, good guy and always willing to help.
any info on what was the trouble im about to order a couple of new pcms and i sont like surprises like those no start
all the way from Tampico bay Mexico
I bet it has something to the 4 digit pin code needed on New 2019+ Pcms, If you know someone with Witech that should tell you.
