This allows you to separate the problem between ignition and fuel delivery. If the plug quickly fouls out again, you are most likely rich on that cylinder alone. Pull the pressure regulator vacuum line and see if you can smell fuel in the vacuum hose. If so the problem is a leaking diaphragm in your pressure regulator. Most likely the vacuum line will be nearest the malfunctioning cylinder, since that cylinder is sucking the excess fuel from the vacuum line.

Never thought of smelling the vacuum line, you are smart seriously no joke. I'll wait until the excess gas smell from motor dissipates.
I tested the injectors, pull rail method, and they all fire with good spray pattern. Pressure I think is good cause a few injectors shot out before I realized I needed to hold them in and have a second person cranking. Going to check spark again.
Again thank all of you for your input.
