I did an egr delete and have codes for that but I was told that you didn't have to do any tuning except to keep the light off. Correct?

Technically you don't even HAVE to do that if you don't mind the CEL being on.

With the drop or so coming out of the rail it still holds rail pressure and builds to about 20000 cranking with the solenoid un plugged at the pump and with the valve on the rail un plugged it builds over 1200. If I read everything correctly that would mean that both are good. I would hate to replace one or the other when they test good and I only get a drop or so of fuel coming out. I'm not discounting or ignoring your input. But everything Im testing and seeing shows they are good.

If you only got one drop, that was probably just residual sitting in the port. It does sound like 1) the FPS is working as it should be to start. 2) signal is getting from the ECM and causing it to function, so we can probably rule the FPS out for the time being.
When you try to start it just cranks with nothing going on, or does it sometimes begin to start then just quit?
