Help !! Hopefully someone can help,my 2009 Equator will not start in cold weather(below freezing).The engine just turns over but will not start,battery is strong,but if you jump battery it starts.Truck has only 3,000 miles. Its been in dealers service for a week and prior time for three days . They changed crank sensor but that didn't do anything. Looks like they have no idea whats causing this to happen. If anyone has had this problem please let me know what the fix is so I can get my truck back in working order.
