1G fuel pressure regulator

My car is having startup issues and I am starting to believe that my fuel pressure regulator is bad my fuel pressure reads 38psi with the car running and when I unplug the vacuum line from the fpr the psi does not change so is my fpr bad

Maybe the vacuum line is bad/blocked and the FPR isn't seeing manifold pressure.
Get a hand vacuum pump and try supplying vacuum at the nipple to the FPR and see what happens.

Is the vacuum line coming from the stock nipple location on the manifold?

Yes the hose is in its original spot on the manifold and if you put your finger on the end of the hose you can feel the vacuum so I don't believe that its plugged or bad I also have my boost gauge tapped off of that hose and it works perfect
