Have you replaced the fuel filter? How did you "check" the fuel pump? Did you do a fuel pressure test? If so, was the pressure within specs? How about the fuel pressure regulator? You are obviously getting spark so its fuel related. Sitting for that long I must ask, did you replace the old gas? Year old gasoline is not good. Does it have a lacquer smell to it? Good luck.
