You may have burned up a fuselink, most of them are located on the positive side of the starter relay on the inner fender, they will have little tags on them that will say 20GA or 15GA and will be different colors.

Oh boy. Fuseable links, fuses and pinched wire looms. Find the shorted wire(s) first and repair them before you replace any fuses or links otherwise, you'll blow them again. DO NOT put a larger fuse in the old one's place - you could burn the truck down.
