The Nissan Path

I have a 2000 Pathfinder and the fuel pump quit working . I bought a new pump and replaced it but still not working.I have no tester and and dont know how to test the relay or if it could be the sending unit. Any suggestions.

Probably not a problem with the fuel pump then. Relays are cheap. Just swap one in and see if that works. Check your fuses too. Sounds like its something electrical... Hopefully you already have it working by now.
