When you say "click", do you mean that the engine is not turning over at all? You know, "rrrr, rrrr, rrrrr, vrooom", but without the "vrooom" at the end? If it is not turning over at all, then I would start with the battery to make sure it is fully charged and your connectors are clean and tight. Check the battery cables also to make sure they are connected properly at both ends. If you seized your engine after one bath, then Nissan ought to be buying you a new one... I don't think you have a seized engine
