Trying to empty fuel tank by jumping fuel pump relay on the vehicle listed above ES model. The car has been sitting for a very long time for repairs that have finally been completed. I am not sure which two pins to jump. The relay pins aren't labeled with numbers (85, 87, etc.) Commonly found on car relay. Here is the picture of the relay and how the pins are labelled.

Thank you for any help.

Good call there, no terminal marking is difficult because now you need to look at the wiring from under the fuse/relay panel. Here are the wiring diagrams for the relay so you can see how it works but I would be careful because you can short out the PCM. Two of the terminals are grounds and the PCM supplies power to the pump, you might want to find the wht/blk wire at the fuel tank and supply power to it instead. Check out the images (below). Please let us know what happens.
