I believe that dehydration is your biggest problem now. Did you rehydrate him at all before beginning to feed him? Rule #1 is First warm them up, then rehydrate and then begin feeding, even if you have to give hydration only for a half a day before starting food. They can't digest properly if either cool or dehydrated.
I would use either pedialyte or a homemade rehydration recipe WITH the salt for one day. It will help with his electrolyte level. One day only for that.
