2006 Ram 3500 Cummins ignition key won't start truck
 

I just finished replacing the front end parts from a accident.(clutch resivor,fuse box,fender hood,etc..)All electrical components work as far as I can tell.The key will not start the truck.I took a jumper wire and jumped the starter and the truck starts and runs fine.The wire I jumped came out of the fire wall and ran down to the starter (14gage maybe) I unplugged this wire at the firewall and jumped it to a hot wire and the truck started.Is there a reset button or something I need to reset so the key will work?
