Bad fuel distributor usually doesn't cause the car to fail to run, although that's possible. usual senario is that fuel consumption goes sky high and it blows black smoke from internal corrosion and loss of pressure integrity.

You must check for fuel pressure, fuel delivery, spark, and movement of air flow meter flap before condeming the fuel distributor.

They will go bad on sitting, but since the replacement didn't fix the problem, even partially, I don't think it's bad already, and a couple months isn't a problem, a couple years is.

More likely the fuel pumps are bad or the accumulator is bad and plugging the fuel line if you get no fuel at all.

Also make sure you have fuel delivered to the engine, and not water from condensation or sabatoge....
