fuel pump not humming

My husband has a 95 blazer. He put a fuel pump in it last night. He tested it before he installed it, and it showed that it worked. Well, after he got it put in and tried to start his blazer, it wouldn't work. No humming when he turned the key. He is beside himself, and wants to know if anyone has any clue of what to do to check for any other problems that the truck might be having.

are the fuses good?

Also, check the relay. There is a test wire located near the relay that 12V can be applied to for checking the circuit.

Check the fuel pump relay. It's in the glove box on the 95 Blazer. I had the same problem, replaced the relay and it worked great.

Good Luck
