Sounds like the cold start injector is operating when it should not. When the engine is warm the cold start injector is not needed and should not operate. When the engine is cold it is needed, but only for a few seconds. If the injector is open extra fuel is being delivered to the engine causing it to run rich, or in your case so rich that it wont even start. Try removing the connector on the cold start valve and see what happens. It is possible that the cold start injector is leaking or sticking open. I would pull the plug and see if there is any difference in the way it starts.
