Go get an automotive "Stethoscope" from Kragens or Autozone and put it up against the injectors to listen for clicking. You can also do it with a long screwdriver to your ear.
Could be a clogged fuel filter too.

Check for vaccuum leaks. Also, try setting the idle using the adjuster screw. If it start then it is getting fuel (at least for a while). Also, check your plugs to see if they are fouled.

Have you checked the fuel pump run relay? It sounds like it is pressurizing the system at statup, but then the run relay isnt kicking in after startup to keep the engine running. You could test it by jumpimg across the pigtail that plugs into it.
