MONTE-SS

I am helping someone work on a 1992 Blazer they recently got for cheap, and were told it had an incorrect fuel pump which was causing it to run extremely rich, which you could see clearly. So today we drop the tank and replace the pump with a brand new one, put it all back together and now the fuel is coming out slowly in droplets, not misting like it's supposed to. Obviously it is not enough for the truck to run on, so it won't start without pouring gas into the throttle body, which only helps it run for a few seconds and then die. What now?
