Fuel pump relay switch location

Where exactly is the fuel pump relay switch located? I recently tried to get my car to start after sitting idle for eight years due to motor problems. I installed another engine out of a 1991 Festiva and replaced all gaskets and timing belt, installed new electric fuel pump, but it will not pump fuel up the gas line! The only negative thing I did was not draining the old gas out of the tank, since it only had about two or three gallons in it. I put a can of Sea Foam and added five gallons of gas to the tank.

Thanks
