Question about Chevrolet Cars & Trucks
Replaced fuel pump 3 months ago ran fine than one day would not start again
Considering it ran fine after pump replacement for awhile then it is probably a fuel issue. Couple things it could be. 1. you could have a ton of sediment in gas tank and it keeps clogging up your pump. 2. you could have blocked fuel filter and or clogged injectors.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

sounds like fuel pump pressure. I had the same thing happen to me in a Lincoln mark VII and the electrical connection was shorting out in the fuel pump. I changed the fuel pump..Returned under warranty) put the new one on with filter and had no problem with it.

You need to loosen three (1,3, and 5 are the easiest to get to) of the injector lines at the cylinder head with a 19 mm wrench. Have someone crank the motor until you see fuel come out. Immediately start to tighten the lines, while the motor is still cranking. The motor will start to catch as the lines get tightened. Let it run a few minutes to eliminate the rest of the air.
I've had to do this several times on my 99 Ram because of a messed up sending unit telling me I still had a half tank.
The mechanics at Mt. Clemens Dodge taught me this. Good Luck.
