my truck is a 4 door 4 wheel drive 4.3L V6. The truck was running great i shut it off and it wouldn't start again. If you pour gas into the intake it will run for a few seconds. I have been told its one of three things and i want to work cheapest to more expensive. I have already changed my fuel filter and no change. I have heard about a fuel pump relay/fuse but there is no fuse labeled with anything to do with fuel that i have seen if you know where this can be found please let me know
fuel pump relay on 1996 Chevrolet Blazer
Chances are very good that the fuel pump has failed on your 1996 Chevrolet Blazer. If you would like to do some checks at the fuel pump relay it is located in the relay center located behind the glove box (there is an access cover in the clove box for the relays). The fuel pump fuse is located in the instrument panel fuse box - labeled ECM BATT.
My 1997 chevy blazer has issues starting. When the problem started, It would turn over the starter but I would not hear the seatbelt noise. Try again and the seatbelt noise could be heard and it would start instantly. Over the next week it got harder and harder to start. I don't even need to turn it over all the way. If I don't hear the seatbelt noise it will not start. If I hear it it starts on the first crank of the starter. Sometimes Moving the tilt steering up and down would help. Now it's gotten worse and almost never starts. When it starts it will run forever until I shut it off with no problems.

I am having the same problem, and have checked my fuel pump relay, which is located under the hood in a black box located on the drivers side of the vehicle. I had to unscrew the knob until the lid loosened, and then there is a diagram located on the underside of the lid that will show you which relay is for the fuel pump. Mine was good unfortunately, so I think this is going to cost me...Hope you have a better outcome. Willis M.
