1992 Dodge Spirit Fuel Pump problem

I replaced the fuel pump on my car because it wasn't working. The new one
doesn't work either, so I was thinking that it could be the fuel pump relay,
so I bought one, even though I'm not 100% sure where it is located. I found
some relays located up by the car cattery, but my new relay will only fit
into 2 of the 5 relay slots. But the fuel pump still does not get any power
regardless of which slot I put the new relay into... Could it be something
else? Is there another part that could have went out, such as a fuse or
something? I can't find any fuse related to the fuel system anywhere on the
car. Maybe I'm looking in the wrong area??? I'm totally stumped on this
situation... any ideas???
