It appears that my fuel injection pressure regulator is FUBAR. I have a local recycling yard with several candidate vehicles in it. Is there a quick "junkyard" test that I can perform on non-running engines to know if the pressure regulator is worth taking? Based on the system description, I wonder if you could depress the diaphragm thru the fuel inlet connection using a small diameter pin punch---or does such activity ruin the regulator.
