I was driving on the highway-took an exit-stopped at a stop sugn and my car wouldnt go...it wouldnt even try at all after I had stopped. It was still on -just wouldnt move. It has a full tank of gas... coasted it to the side of the road... had it towed to ny goyse and now it is acting like it doesn't want to turn over. It wont staet with jumper cables attached or off starting fluid. Any idea whats wrong and how expensive to fix?
