Being very cold will cause the engine to crank over slower. It should start though if the fuel and ignition systems are alright. Check for spark while cranking. If there is a large draw on the battery while cranking (bad Battery, or bad connections) the voltage at the engine ECU could go low enough so that there would be no spark. It may help to clean all of the "big" connections from the battery to the engine and frame. In these cold temperature NEVER let the battery go dead. When a battery is very low or dead the electolyte inside is water not acid and can freeze. If a battery is ever frozen then the plates inside buckle and short out to each other greatly reducing it's capacity. NEVER TRY TO JUMP START OR CHARGE A FROZEN BATTERY, IT COULD EXPLODE!!! If it is that cold and the car is not used regularly you should remove the battery from the car and keep it in a warm place.
