sounds like u lost fuel pressure,possibly fuel pump, spray staring fluid inton throttle but make sure u re-connect air hose to throttle before u try to start because of the mass air flow sensor. it wont start u nless connected. hope this helps.
I have 2000 Chevy blazer 4.3 l v6 vortex I had the same problem I would spray starter fluid into the air flirted canester Nd it would start as soon as I stopped spraying the fluid the engine would die first I checked to make sure my gas pump was working in the gas tank second I checked my fuses under the hood and last the fuel pressure so my gas pump was on in the tank fuses were also ok but I had no pressure on the gas line so that ment my gas pump was bad I replaced it after replacing it my blazer fires problems free now
check to make sure they sold you the right fuel pump. they are two pumps for a 4.3 ones a vortek and one is a throtlle body. the eighth digit of the vin will tell you one is a vin w and one is a vin z. the throtlle body only puts out about 11psi of pressure and the vortek puts out about 60psi of pressure.if you put the throttle body pump in a vortek engine there is not enough fuel pressure to run it.
What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!
