Lets start with a theft learn. I suspect you may have blown a fuse for the PCM power. do you have a test light?

Expert:  Tool Hut replied 1 year ago.

here is theft learn procedure

Customer: replied 1 year ago.
It is going to be a couple hours before I can attempt this procedure.
Expert:  Tool Hut replied 1 year ago.

Can you also check for a bown fuse in under hood fuse box? Probably ECM-B

Customer: replied 1 year ago.
I can
Expert:  Tool Hut replied 1 year ago.

OK. Let me know results

Customer: replied 1 year ago.
I verified that the fuse it good. Completed key relearn procedure started truck with same results. Started, ran for 5 seconds and died. Security light stays on does not go out at all.
Customer: replied 1 year ago.
Also verified all fuses related to ecm are good. Gas gauge still shows empty and I know there is 3/4 of a tank. All displays related to fuel mileage, oil filter, fuel filter register dash marks not numerical values.
Expert:  Tool Hut replied 1 year ago.

It is a very good possibility that the PCM has failed. It will need to be programmed if it is changed. I would check all powers and grounds at the PCM before changing it
