You either have a bad starter or ignigtion switch. When you turn the key on does everything else come on? I would check the starter first if you have power to everything.

I would check the fuel pressure regulator, fuel filter, there might be a centrifugal cut-off switch. No output from the crankshaft position sensor would probly cause that. When you turn the key on you should be able to hear the pump run for a couple seconds. If not, could be a short circuit, loose connection, that sorta thing.

sounds like your fuel filter is clogged i would try replacing that then try and run injector cleaner through it

Yes, there is another way to replace the fuel pump of your firebird. Many other cars, like my 1993 mitsubishi 3000GT VR-4, had an access hatch built into the car that you can simply open above the gas tank and fual pump, remove and replace the fuel pump, and close the hatch. I have owned many 82-92 firebirds, and a 1987 GTA I bought, the previous owner had simply cut a hatch right above the location of the fuel pump in the gas tank, peeled the metal back, pulled out and replaced the fuel pump through the hole, and then pushed down the metal and sealed the edges closed. It wasn't real pretty, but it is underneath the back carpet and no one would ever see that repair. So yes, you can replace the fuel pump this way, and I believe you could actually place a hinge on the piece cut out and make a hatch there that looks OK, so you can do the repair again in the future if necessary.
It's a real shame GM did not do this simple thing, put a hinged door above the fuel pump, when they built the cars, like other cars do. If and when I have to replace a fuel pump, I am going to have a hatch put in my firebirds above the fuel pump when the repair is done.

it is called the fuel pump

Check your fuel pump relay

First clarify stock ELECTRIC fuel pump in tank and you say CARBURATOR. If its not EFI , something is not right. Check for a 20A fuel pump fuse, with a 12V test light. IGN ON The oil pressure switch is on the engine block engine type unknown ). It the engine loses oil pressure (i.e. stalls) the fuel pump will shut off. Hope this helps.

There is a fuse that is pig tailed from the positive lead to the battery. Check it. Also you can check to see if you have power to the fuel pump. Take your old pump, and put 12 volts to it, and see if turns on. If it does, then the pump was never the problem.
