Thanks for the input guys, I was leaning that direction and had already told my ucd manager the probability of this being caused by the injectors, I guess I needed some moral support, I doubt that I will be repairing this unit but if I do I will let you all know what happens, Thanks again!

this might seem a little stupid but I waould like to see what you all think of this... 1999 f350 starts normally in warm shop runs fairly good when warm, when cold....35f and lower will not start, I have reploaced glow plug relay, it was smoked. verified glow plug operation fuel supply to filter ok, (have not performed press test yet, when engine is cold (outside) and a injector self test is performed you cannot hear any cycling of the injectors, when warm you can. this is a traded in truck with our used car dept. my initial thoughts are sticking injectors, cut my teeth on 6.0 and am not overly familiar with these older guys. what do you guys think?

so in retrospect when the next one comes in and it passes these (high, low) fuel press tests and you can't duplicate in a reasonable amount of driving time what do you think you would do? My question stems from the fact I have an 8K mile f350 doing the EXACT same thing, AAAARRRRGGGGHHHH!!!!!! BTW DOESNT THE PPT SUCK?!
