I have a 2012 Ford Edge Limited. In May I was driving on the highway and the car just dies. Get it towed and since the battery was being drained we replaced the alternator. After the Alternator we replaced the spark plugs and coil caps. And also got a new battery. We drained and replaced the oil also. Now car will start but when you shift it to drive nothing happens, press the gas pedal and nothing happens. Any clues as to what it could be now?
