1st I would wait and see if u actually killed the yeast maybe another 12 to 24 hours. If nothing seems to be happening re pitch some yeast and you should be fine.
I am curious of where you got your juice; was it bought from a store; was it pasteurized; or was it the fresh pressed orchard stuff. If it was stuff that was pasteurized I wouldn't mess with sulfites, the juice is already sterile. If it was the fresh orchard un-pastuerized...my thoughts on sulfiting is not to do it unless it is absolutely necessary. Even if it was un-pasteurized juice I would have just pitched the yeast on it. Keeping in mind the pitch rate should be big enough for a fast fermentation.
Keep in mind to be sanitized your self.
