Take the vaccum line off the fuel pressure regulator and plug it , then see if it runs better or worse. The vacuum side should be dry with no fuel in it if there is fuel on that side the reulator is bad. Also since you ran it out of fuel change the fuel filter because it has probly sucked up a lot junk from the tank. and that's why your not getting any or little return it just isn't pumping enough to even keep the car running so its not gonna send any back
