problem car starting?

If you can jump-start the car after discovering that the engine won't crank in the morning, my guess is that you have something that is draining your battery overnight to the point that the battery is dead by morning. You (or a shop) can test for excessive current draw on the battery as the vehicle is parked to confirm and if that's the problem, you (or a shop) will need to figure out what's drawing more power than its supposed to when the vehicle is not running and correct it or the battery will keep dying. A workaround to this problem (without solving the cause) would be to disconnect the battery cables from the car as it sits overnight, then reconnect them in the morning to prevent whatever's drawing too much power from killing the battery overnight.

If you can't start the car by jump starting it then I'd lean more toward a loose connection to the battery, to the starter or possibly from the alternator to the battery, something that's preventing current from getting either to the battery to charge it or from the battery to the starter to start it. Good luck.

Starters don't freeze. Guess again.
