There is a bulletin for the no start and for your codes stored in the ECM , the first thing to do is check the oil level this will affect the cam sprockets and trigger a failure code, there is also a voluntary recall for the cam sensors for a no start condition,graphicgraphic I would have Nissan install the sensors for you, This will be free at the dealer it is a recall here are the bulletins . Thanks let me know if you have more questions, ROY!
