Hook battery cables up back words truck will not crank

I do not understand the question- "turning over" is the same as "cranking"- this terminology comes from the old Archaic Days when cars had a hand crank- do you mean "turn over but not fire"? Jumper cables will destroy a car's electronics even when they are hooked up right- first step- throw them in the trash and NEVER use them again- always have a good battery and say no to those poor souls who do not think it is important to go into the winter with a fresh battery- now, that is a simple truck, and it should be easy to find out why it is not starting- still getting fuel? then it is the ignition system- did you blow the ignition module in your electronic distributor? or a fusible link somewhere near the battery? on the alternator? usually when jumping an alternator diode will blow- but this will only keep it from charging, not starting- are you sure there isn't some other problem?
