1988 Pontiac Firebird still got the fuel pump blues

So I have a 88 trans am Gta, and the car died on me, on a really cold night. All it would do is crank over, and the engine is a 350tpi, so when you turn the key to the accessory on position before starting the car you would hear the fuel pump turn on and shoot fuel to the motor, I dont hear the pump turning on, so I got some starting fluid and shot it into the throttle body, and the car starts for a second. So I figured the fuel pump was bad. I replaced the fuel pump, it was a pain but I did the job right, still nothing, so I than replaced the fuel pump relay, and checked all the related fuel pump fuses, which were not blown. So I heard about this web site and asked about my fuel pump blues, and you guys reccomended to check the oil pressure switch. I replaced the oil pressure switch and still am not getting any response from the fuel pump. I am good with cars, not the best, but I am just really stumped and puzzled right now and need the assistance of a jedi mechaninc, Please any ideas or suggestions, because I am lost, and I really want to drive my cool Trans am
