Default Obd2 won’t communicate
So like I said I bought this truck from an auction with no key got one cut but at the dealer they couldn’t communicate with it so I could program the key. Would start for 1-2 sec then shut down. I tried to test the plug with a test light and the ground pins 4 and 5 wouldn’t light or the positive number 16

If you have no voltage at pin 16 maybe you have a bad fuse. The fuse for the DTC usually power other stuff but I don't know what it would be for your truck with looking at the wiring diagram for your model.
