Fuel or Spark? For fuel you can pour a small amount of gas directly in the Throttle Body and crank the engine. If it fires and then dies you know it is fuel and most likely the pump. For spark if you have a timing light you can put the pick up on a plug wire and crank the engine if the timing light lights you have spark. If you do not have spark at the plug connect the light to the coil wire. If the timing light lights on the coil wire than you have a distributer problem. (Cap, Rotor, Pickup or the whole distributer). If you do not have spark on the coil wire than it is most likely the coil.

If you have no spark, it could be your ignition control module or coil. Both are cheap and can be done in your driveway. I just had the same symptoms and turned out to be my ignition control module. In my truck it was under the distributor cap.

If you can't hear the pump then its probably something to do with the pump.. It may just be a bad ground (happened to me) or bad pump.

Did you replace the fuel filter as well? if the tank is old, removing the sending unit/pump can stir up sentiments in the tank which can clog the filter. If it ran fine before it died, then you replaced the pump, and now it has a miss, I would guess fuel filter now, fairly common after removing and replacing the pump.
