Been between 5-10 degrees the last 2 days and wife drove the truck due to snow. She called today and said it wouldn't start......sounds to me like the starter is just spinning not catching at all to try and turn the motor over. My guess is the last 2 days of cold starts trashed the starter? My concern now is though with the key in on position is the constant whine sounding like it's coming from the rear of the truck? Now the truck is in a parking lot and wont start.
