Did this happen before or after you changed the batteries?

 

[clyde69]

after i changed them and it ran before i changed them

do you have an alarm? or remote starter? check the BCM fuse under hood.

Maybe the VAT system was enabled somehow?

what is the vat and how do i check it

VAT stands for Vehicle Anti-Theft system. Most likely thats not the case just because you changed the batteries. However I have see stranger things happen. Like Vrabel said, you don't have an aftermarket alarm or anything like that on the truck do you? One thing you could try is turn the key on, attempt to start the truck, then leave the key in the on position for ten minutes. After ten minutes pass cycle the key and attempt to star the truck again.
