My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
It is possible this issue is due to a weak or dead battery causing this fault here.Even though you have an interior light there may not be enough voltage or amperage from the battery to allow starting.I would see if you can try and recharge the battery or jump start the vehicle and see if it starts then.If it does I would have the battery tested to see if it needs replaced.If it still does not start I would have the starter tested as this can fail and cause a no crank no start issue needing replaced.
