Might be worth taking the EGR valve off and cleaning it just in case it is not fully seated. Also check the PCV valve and the condition of any rubber connectors and elbows to it.

Dang case you are on this like a madman, I am throwing you some reps...

Fomocofan, I'd keep following what he says, he won't steer you wrong.
I wonder though, you mentioned this truck sat for three weeks prior to doing this. Did the truck often sit for long periods of time unused? I wonder how the battery and charging system are doing.

I will give it a try with the EGR valve. Also I pinched the fuel return line and had no change in fuel pressure, the guy that told me to try that said it should shoot way up but the needle didn't move, he thinks the pressure regulator is not working, any thoughts on that? Eponator to answer your ? the truck does not normaly sit for more than two days without running, that was a rarety. The battery is not the best, I will have to replace it before winter, the alt. is good. I am greatful for your ideas. It looks like my schedule is packed this week, and I wont be able to try anything until later in the week, but I will let you know my progress and try to get your advice then. Thanks

As many of the others have mentioned the fuel pressure, with vacuum at the FPR, is just on the edge of low so a new FPR may be worth trying.
