IdahoCowboy,
I'll check with my friend, he's pretty good with the Powerstrokes. Did you check the oil? If it's too low, it won't start I've heard, I think it has something to do with the high pressure oil pump to run the injectors or something. Keep us informed, hopefully someone on here will figure it out for you. If I find out anything I'll let you know-I know it's a pain when something is wrong with the truck!
