Is there a way to check the fuel pressure regulator? I mean, I know how to test fuel pressure, and I know it should only drop 5-7psi upon shut-off, but is there a way to actually test each potential problem individually?
Like I said, I replaced the pump assembly once already with a newer model, so i'll be testing the regulator first, if there is a simple way to do it.
As far as injectors are concerned, could they be leaking fuel into the cylinders, and back into the tank? I'm confused on that one.
