If the FPR is at least mostly functioning... and you pull the vacuum line off the FPR and gasoline does not come out of it, and if there isn't a strong smell of gasoline, the FPR is mostly if not completely functioning. You may be running rich, but not to the point of flooding the cylinders with fuel, it would at most give you black exhaust or poor running but it will run.
consider trying this. pull the fuel pump fuse, pull the plugs, crank to air out the cylinders, replace the plugs with either other ones or burn those off with a match or lighter, use either carb cleaner or brake cleaner and pull a vacuum line off the intake plenum and with the spray tube applicator spray directly into the plenum to a count of five, replace the vacuum like and crank. it if start to start, and then quits due to no more go juice, you most likely have sufficient spark. If this passes then something is causing the injectors to stay open. Again, check all of the connections and grounds at the front of the fuel rail. Also look for a pinched wire, have you done anywork in that area? We had this very thing happen before a race, took me four hours to figure it out. I talked to my friend Walter Wong about it while in extremus, he gave me some ideas that didn't pan out. I later conversed with Walter and to share my findings, he said that the issues I had matched the solution I discovered, needed to replace TWO of the ground lines that broke, I believe there are five or six with a couple of them crimped into those solderless connectors with the round eye for torx bolts that screw into the head. The grounds looked ok, but further poking proved that the wire was broken inside the insulation and only looked good.
