2000 GMC C1500 Wont start

I have a 2000 gmc sierra and was involved in a minor accident, my son ran over a tree that was in the middle of a dirt road, he ran over the tree and the truck now it will crank but will not start.Is there a fuel reset switch somewhere on the truck or is sonething else wrong,,,, the fuel pump is not getting power to the pump. when I turn the switch to the run the pump used to make noise but now nothing, any help would be greatful thanks EDDIE
