Blessing for the quick response! I will indeed do the research to identify the correct security system. Thanks!
I did read the owners manual and it spoke of the Passlock system, but unlike what you describe, the vehicle would NOT turn over. In fact all the other bells and whistles power up, but when turning the key, you don’t even get so much as a click… or clack!!! So, as suggested, I will find the codes, check with the G-man and write more later!!!
Interestingly enough, I read a post on a similar problem where it was suggested leaving the key in the ignition for 10 - 30 minutes to allow the chip to reset itself. Being that I still don’t think there is a chip there, I tried this measure as a last resort… and of course prayed for Divine intervention!!! After the 30 minutes had passed, my son went out and the truck turned over for him!!! Can I hear an AMEN from the chior please!!! 
So for now, he’s up and running. Needless to say I will follow through with your advice as I fear this odd ball event will rear its ulgy head in the future. It would be nice to have a clear understanding of why and how to fix it if it should reoccur. Thanks for all you do! I’ll be back to bother you once I have more information!!!
Best Wishes Always! :0)
