The high-speed fan relay in under the hood on the firewall left of center. If I remember correctly, there are 3 relays on the 1996. The relay closest to the passenger side is the high-speed relay.

Your 1996 Chevrolet Blazer may not start due to a faulty ignition switch. The electronic fuel pump may also be faulty and need to be changed.
Its not on a fuse so to speak its a relay drivers side fuse panel at the top marked (A)

Take out all the junk in the glove compartment and look in back. You will see a door marked "relays". Remove the door and the fuel pump relay would be the first one on the left.
