Tried turning on the truck yesterday and it decided to not do such thing. I drove it the day before and all was well. It tried to start for a fraction of a second and then nothing. Now when turning the key to try to start it there is no noise whatsoever from the vehicle. I'm trying to figure out if it is a bad starter or if my ignition is bad. I've ruled out the engine being seized as I have pulled out the spark plugs perfectly fine and I was under the impression that the compression would have made that difficult. Needs some help here. I can do the work at the house, just need to know which direction to go.

First make sure the battery connections are clean and tight. Make sure the battery is fully charged and tests good.

Does the fender mounted starter solenoid make a clacking noise when you attempt to crank the engine?

On that solenoid you have the main battery cable from the battery positive on one stud, on the other a large cable going to the starter. Take a large screwdriver and cross both large cable studs. The starter should turn if all is well. If not you will need to get out a voltmeter to do some voltage drop testing to confirm or deny a bad starter. If it does turn. pull off the small wire of the magnetic switch and jump from the battery positive stud to the little stud that wire was on. If it again turns the starter you have confirmed the magnetic switch is working and you need to find out why the signal on the small wire isn't happening. These trucks were known for a few issues with this. One was the ignition switch going out, the other was the metal pivot in the column that connects to the actuating rod breaking on one side. You would be able to turn the key on but not engage the starter.
I read this thread rather fast, so didn't see if this was an automatic or stick.
Don't throw any parts at it just yet, but do the tests I mentioned to narrow this down so we know the next step to take. We want you to spend money on parts that are known bad, not go broke changing good ones. On the upside this truck isn't too hard to work on.
Post back with your findings and we'll get you on the road soon.
