I'm guessing it turns over. If there's no spark, then something is wrong with the electrical system somewhere. That could be in the coil, distributor, wiring, or the computer. It could be something simple and inexpensive, or something complicated and very expensive. Sorry I can't be of any other help, but without having the truck right in front of me there is no way for me to know what exactly it is doing when it's cranked over.
