100 Psi Fuel Pressure!!!

Okay I got my new car as a shell, it was sitting for more than a year.
It had about ahalf a tank of bad gas in it when we switched everything over an got it runnin.I have a Nismo PFR and 300 ZX fuel pump when you turn the screw to adjust it, the pressure does not respond at all it reads 100 psi until I turn the car off then it reads like 40 psi.My friends think that my injectors and fuel pump are clogged up but the car runs fine.I would like to know if any of you guys have delt with this or know someone else that had a similar problem like this???

P.S. I put a new fuel filter in and checked the lines in the bay.I also put a stock FPR on just in case for now until I get this fixed.And I changed the gauge!!!

blocked return line?
undo your return line and put a hose on there going into a bucket...then run the car and see if the pressure is normal. I've heard of people setting lifts on fuel lines before, and fixed one myself before.
