I was having stalling problems with my '94 S10 Blazer (4.3L engine). Everything I read suggested my fuel pressure regulator was leaking. Upon removing the plenum I discovered one of my fuel control lines was leaking. I replaced both the regulator and the fuel lines. Instead of my truck starting up and purring nicely, I took everything apart to make sure I assembled everything correctly (everything looked fine). I can see the fuel lines filling up when I turn the fuel pump on. I also removed the regulator during checkout and found gas there (which tells me the gas got that far). Is there anything I'm missing in terms of checkout? My next step is to tow the car to a garage and spend ALOT of money to get this fixed. I'm hoping has some ideas.
Cheers!

I think you have a fuel pressure problem. These engines require about 60 psi just to stay running. The injectors have spring loaded ball seats in the and it requires a certain amount of pressure just to open them.
Check the fuel pressure.
