The “Fuel Pressure Regulator” ( FPR) is another can with a spring-loaded diaphragm, but it is located in the engine compartment, next to the Fuel Distributor.
Is that much correct?
...
With that 85 psi going into the FPR, I see nothing at the Fuel Distributor. Am I correct is believing that mans the FP is bad?

If you're getting 85 psi then your accumulator and fuel pump are in excellent shape. If you measured that pressure at a correct port in the fuel distributor then you FPR is likely good enough to get the car to run.
Your system pressure is supposed to be between 75-80psi

to check if your fuel injectors/fuel distributor is good what you may want to do is set up something similar as in this video (I did that on my SE to check my injectors/fuel dist):
