If it's fuel related, I would think you should be able to shoot some of that starter-fluid-in-a-can stuff into the intake and it should fire up and run.

I had similar (but not exactly the same) problems that I thought were fuel-related. After a long diagnosis with a mechanic we determined the problem was a cracked distributor rotor that was providing a ground path for the spark. Might be worth checking your distributor rotor. If nothing else, it's a quick check... <img src="/forums/images/graemlins/kewl.gif" alt="" />

Good luck with tracing this down!
