Question about 2002 Chevrolet Blazer
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.
