    did they check the fuel pressure? it has to be 62 lbs or more to make it run.
    after the pump was changed, there is a common failure of the connector at the pump. it is usually included in the box for replacement.
    there is no switch, just a relay located in the relay center.

    BUT I DON'T KNOW WHERE THE RELAY CENTER IS LOCATED ON MY 1993 CHEVY S-10 BLAZER. HOW DO I CHECK FOR A POSSIBLE FAILURE OF THE CONNECTOR AT THE PUMP WITH THE TANK AND LINES BACK CONNECTED?

    you have to drop the tank again to acess the connector.
    the relay center is under the hood in the main fuse block

    sorry
