There is your problem. It should build up to 37-39 lbs on first turn of key and hold there. IIRC. Surely either a pump or pressure regulator issue.
What is pressure at idle? Mid throttle?
Does pump make any noise like screeching or anything like that?
How long will it hold 36-39 lbs?
The problem is it should build higher pressure initially.
