It's not my car, I'm trying to help a friend. I'm trying to find out where the fuel pump relay for the 12a motor of an 85 RX-7 is . Also, if anyone knows what colors the wires are to it that would be nice.

 

I just dealt with this today, actually. Be aware that on the 84-85 (other years also?) the fuel pump does not come on if the ignition is in the ON position. The car must be running AND be in the ON position in order for it to run. I don't know if there's a relay or not. I don't think there is..
The wires can be located underneath the driver's side cubby hole. Take out the ~5 black screws, lift out the cubby hole thing, unplug the light wires and peel back the insulation. (Note the rust here also, heh) Look for two wires encased in a black sheeth. This sheeth goes down into a grommet that is directly above the fuel pump. There's also a convenient wire plug piece to remove the fuel pump.
On my 84 they are Black, and Black with a White stripe.
Black being negative of course.
If you ran outta gas, you'll just keep have to turning it over, or put voltage across the pump in order to prime it. Letting it sit for 30-60 minutes after you've done either of these things helps also if it gets stubborn.
