Alternator would have nothing to do with cranking. If the battery has a charge the starter should still turn.

Hey guys, thanks for all the help. Heres what I've done so far. The battery has plenty of juice, Lights and dash are all fully functional and battery reads full power. Have tried tapping starter while someone else cranked, no luck. I have checked all of the fuses and relays and they all seem to be fine. I have even swapped good relays from other locations to see if they would work. I spoke to the dealer and they suspect it might be the BCM. Keep the suggestions coming please.

Have you checked the leads at the starter to see if you are getting power to it? I would start there and trace backwards. If you get power there when you turn the key, then you know it is a starter/solenoid problem. If you get no power there, then find the next component up. In the old days that would be the ignition switch, but I am not sure if there are any modules or anything between the switch and starter on these trucks.

Solution: Took truck to dealer and they replaced the ignition control module. This solved all the issues.
