Pressure should be building up to 36PSI or so.
Seems the pump is easily getting you there(a good thing), and the regulator is dropping the pressure so the injectors don't have the pressure to make it into the cylinder(s).
From post #26;
Did you remove the PR and push it off is seat? All it takes is a tiny fleck of crap to keep it from sealing and the pressure just leaks.... Wipe seal with Q-tip if need be.
I removed it from the plastic housing yes. Removed the o ring and as you can see in the last image i have it removed and hooked up to an air pressure line and a pressure gage. Is that what you mean by unseating it? By visual inspection it seems to be unable to be dissassembled any further.. I cannot blow air through it via my mouth but 20psi from the air gun is blowing right through.
