No, Jack does not survive or come back from the dead in the 1997 film Titanic. A fan created a fake trailer for a nonexistent movie called Titanic 2: The Surface, in which Jack is discovered 100 years later, frozen and unconscious but still alive, and is thawed out to live in the future. But this is not part of the official storyline for the film.
