If someone was injured in a car accident and both parties didnt have insurance and you was the passenger what can i do. I have broken ribs and stitche

You may be out of luck! However, just because someone does not have insurance does not relieve them of financial responsibility if they are at fault. You can still sue them and collect from any assets that they might have. You can either do this through a personal injury attorney or file your own claim through your local court system.  You should talk with a personal injury attorney before making that decision.
