I hear you TM, and I should reread everything on the post. Where I am coming from is the fuel could be in the bowls and there still could be no pressure pumping the fuel further, but again, the car should burn the fuel in the bowls; perhaps the pump is weak.
I thought he said it runs on starting fluid. I would think if he kept on pouring start fluid it would use the fuel in the tank at some point and keep running
When I have had similar conditions, the plugs are usually fouled out and will not burn the fuel. I would replace the plugs and squirt a little staring fluid and the car starts and warms up engine fixing the problem which is usally caused by sitting
What John suggested with the choke is also a large potential problem here.
