My son took my truck off roading in the feilds. of course he got stuck in the mud. with shovles and friends he got it backed out and ran into a pile of rocks backwords. the truck stalled and wont restart. No fuel to engine. Checked for power at fuel pump fuse under hodd and no powerwith key on, cranking, cycleing on and off. test from positive to each wire connected to fuse shos ground. i figgure there must be a wire pulled or shorted. i cant fid one. any ideas?

I don't know how far up the pile of rocks your son drove it, but it is possible he set off a roll over sensor that shuts fuel off to engine. Try un-hooking the battery for a few minutes and re-try. This should erase any other odd codes in memory also.
