Look in the fuse box under the hood. Find fuse "ECM B" which is on circuit 120 which excites the fuel pump relay. This is the fuse you want to inspect. The relay pin next to it is controlled by the PCM. The other 2 pins on the relay control the pump and the other the prime circuit.

1997 chevy s10 blazerdash wont light up when key
the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!
