I was driving my 2002 Nissan Sentra car today on the freeway and it took a dump on me. I was driving 60 mph on the freeway when it lost power, and the tach dropped to zero. Now the car will not start. When you try and start it it like normal but it not turn over. When it lost power the idiot lights came on 4 the oil, service soon and the battery. What could have caused this? How much am I possibly looking at in repair costs?
