Okay my fuel pump shut down on me the other day while driving and thus my car died. I replaced the fuel pump thinking bam it would be fixed, but alas it doesnt pump. When I checked the wire harness i found it was only getting about 3 volts of power as opposed to 12 which it needs. I replaced the relay with a used one I had laying around and it still didn't work. What else is there to do? Please help
