If, from sitting a long time, the fuel pressure regulator (FPR) is stuck closed, the pressure in the lower chambers will indeed be too high, causing fuel cut-off.
Loosen the return line fitting on the FPR, and cycle the pumps. If nothing leaks out, the regulator is likely stuck.

Okay, this is what I just learned. I broke the fuel return line at the airconditioning hose (why do you cool fuel going back to the tank?)
I took the connections loose at the AC line and tried to blow air back into the tank. I would think that you would be able to do that and hear the air going into the tank etc., but I could not get any air through at 100 psi plus. I took the short fuel return line loose at the AC line that went to the fuel pressure regulator, and ran it into a jar. Voila the car started right up and ran till I shut it off the fuel was filling up the jar! Hurray, now what. Has anyone heard of a return line clogging up like that?
Next, I plan loosening the steel return line st the tank, to try blowing air through it again. I'll report back if I have any luck.
Thanks for the feed back
