Shut off while driving, cranks will not start

I was driving along, and my car just shut off. The engine cranks but won't start. I checked the fuel pump fuse, and it seems fine. I switched relays like suggested with no change. I could not hear the fuel pump kick on. I removed the pump connector to test for power. I believe the blue/black wire is the power wire. With the key on there was no power. When I cranked the engine, I got power through that wire. Is it a bad fuel pump or should I check something else? I am on disability and cannot afford a mechanic or to replace a lot of random parts. Thanks in advance.
