Fuel pump relay or wires.

19887 s10 blazer v6 2.8l. My car just broke down on me monday and I believed it was the fuel pump, when I turned the key on the fuel pump didnt kick on so I towed it home and droped the gass tank and tested the fuel pumpand it worked fine so my next guess was that it was the fuel pump relay so I messed with the wires some and then the fuel pump kicked on. So I took it for a test drive and stoped for about 2 hours and left it off and whe ni got back into the car everything worked fine then when I got back to my house I shut my car off and then tried to start it up and again the fuel pump wasnt kicking on so I went and bought a new relay and it still isnt working. I am just wondering if there could be a bad wire conection somewhere and where all the conections for the fuel pump are located.

I had the same intermittent experience with mine. It ended up being the ground wire connection at the fuel tank sending unit as it was badly rusted and corroded. Also be sure to clean the ground connection where the fuel tank harness connects to the frame.
