Im a bit confused here 91 blazers dont have carburators stock and if it does then it has been modified other than that check to see if you have power getting to the fuel pump also question did you reinstall the ground strap to the fuel pump. check to see if you get power to the fuel pump relay. These are all questions I would Have done before pulling out a fuel pump. Note that you might want to have a friend help you cause if you turn the key to the on position the fuel pump cicuit is only energized by the computer for about 2 seconds

There are many oil seals in that vehicle, need to know which ones you changed.

1981 Chevy blazer with a 350 recently it has gotten to where you crank and crank doesn't want to run if you get it running it dies if you push brake in or try to put in gear Any suggestions?

It sounds like the Blazer has either jumped time or has a vacuum leak. Check the timing chain and tensioner as well as the vacuum system. If memory serves me right, that 81 Blazer still had a carburetor. The fuel filter may be plugged up. They are small and plug up easily. The fuel filter is located in the fuel inlet fitting at the carburetor. The fuel line nut takes a 5/8" wrench to remove it and the fuel filter housing nut takes a 1" wrench to remove it. Take note as to how the fuel filter came out and be sure to put the new one in the same way and don't over tighten it.

Where is Fuel Filter Locations on 1984 Chevy van g20?

Assuming this van is still carbureted, the fuel filter is located inside the fuel line fitting just as it enters the carburetor. It takes a 5/8" wrench to remove the fuel line and a 1" wrench to remove the fitting from the carburetor. Take note of the positioning of the filter so not to install the new one backwards.
