What else do i need to 'check' off my list?

Thank you for answering my good man, you are in the right spot of what was wrong. needs spark, fuel/air, and compression, I disconnected the main coil from the distribution cap, put a spark plug on the end of the wire, grounded it with a jumper cable, and tried starting it, the spark was orange. which means there was no where near a strong enough spark to run the truck. it shjouldve been without any doubts, Blue or maybe even close to white. So replaced the coil and filled all the fluids to make sure it had no leaks in the water system while running, had to fix a few hose clamps and it is now running very well!
