Those are actually pretty simple systems. I am kind of with Allen here. Sounds like the fuel pressure regulator shot craps. If the throttle body has been done that eliminates the injectors leaving fuel pressure regulator. Pull the vacuum line off of the fuel pressure regulator and if it is wet and full of fuel there's your problem. There should be no fuel in that line. When the diaphragm goes in the regulator the manifold vacuum just sucks fuel through the vacuum line and they run super rich if you can even keep them running. And yes do change the oil. I bet if you pull the dip stick it shows over full due to fuel in the oil.
