Drove it to the store, came back home, shut it off and the fuel pump kept making that whining noise like it was running, so I popped the hood and looked at the relay and it was smoking/already melting, i managed to pull it out and it was hot enough to melt the solder off the contacts so the socket it plugs into is trash.

What's the easiest way to fix this?
Is it possible to jumper it so I can get to and from work until I can get it properly fixed? If so what pins would would get jumped to where?

How do I remove the socket for the fuel pump relay thats in between the firewall, and where does the wire go to? do I have to take apart the dash to get to it?

Hey, I'm guessing by the time you get this you will already have your problem resolved, but generally if the fuel pump relay is melting it's because high current is being drawn by the circuit (ie the fuel pump motor is going bad).

If your '91 is like my '87 then the relay itself is the protective device and under normal circumstances you could use a jumper in it's place with no issues. If you do I would suggest putting in something like a 30 amp fuse in line with the jumper to avoid a potential electrical fire. Beyond that I would say it's actually probably time to replace the fuel pump. Again, if it's at all like my '87 then the fuel pump is pretty easy to replace.

I replied to this earlier but my reply didn't go through?

If your '91 is like my '87 then the relay is the protective device between the battery and the pump. If the relay is melting then chances are the circuit is drawing too much current (ie the fuel pump motor is going bad). In this case it is not a good idea to jumper it.

If you do jumper it, put a fuse in line with the jumper. Say 20 or 30 amps max.

On the plus side, if your '91 is like my '87, then the fuel pump is very easy to replace.

I've never had to remove the socket so I'm sorry but I'm of no help with regards to where the wires go.
