Will replacing to bulb on a 1 area stinger bug zapper make it start zapping again light comes on but does not zap at all?

No, it sounds as if the transformer is out. The transformer provides the zap. If your light was wired to that directly you would not be getting light. Perhaps, an electical fire but no ultraviolet light. I would not be suprised if the brand you have is a Stinger. If it is, junk it, and go buy from Sears. They sell Flowtrons.
