I was driving on the highway and my car just stopped and now it’s not starting

Hello, I hate to say it, but there's simply no guessing that can be done to know what has happened. You simply must have the vehicle tested - hands on - to see what has failed. Base engine concern? Timing? Compression? Fuel delivery? Ignition spark? Air intake concerns? Emission control concerns? Testing will help identify what the concern is. www.repairpal.com/repair-shops
