Idid a search and came up with nothing. Am I the only only one who has this problem?
My 04 Aveo will not start after a long cold night. Will not turn over. No codes. Turn the key....nothing. Battery is good.
Any ideas???

One possibility could be a coolant temperature sensor.

I'd start by checking the Ignition switch, starter relay and starter.
