First off if you don't like longer videos, at least watch the last half of this video. At the bottom of this is the link to the first time working on this truck, It should make the story to this better. The truck has a rebuilt engine and after many many hours of diagnosing I found the problem but not the solution to the problem. Unless someone watching comes up with an idea that I am missing I plan on taking the engine out to find out what's going on.
