Jeff, welcome to the forum.

I've been trying to think of what to say to give you an answer but re-reading your post about the dealer spending 12 hours and coming up empty handed I'm not sure what we can tell you except to try this or that, that hopefully any decent dealer would have already done, especially spending that much time on it.

We have to take for granted, the things that you replaced are of good quality and are working properly but the dealers diagnostics should have shown if they weren't.

I don't know what else to try lol it has really got the best of me!! I have seen many forums about this with no answers

Random thoughts, it cranks? has fuel pressure? security key? remote starter?
netural safety switch? magnet in cam sensor? dirty loose or broken grounds?
bad ignition switch? recheck all fuses, skim module?

I think that would be the place to start....Maybe a bad coil pack.

Has the auto-shutdown-relay circuitry been checked Failure of fuse #13 (20 amp) in the under-hood PDC or the relay will cut power to the coil pack and injectors. If the fuse blows, the fuel pump also fails.
