I hear ya man, its been that cold here a few nights, and for the past two weeks like -40C t really sounds like you have a frozen fuel line likely, go buy some gas line antifreeze and throw it in your tank, if your car is a standard just roller back and forth for a bit and just let it sit for awhile it should work its way through the frozen part, helps too if you can put the car in the sunshine.. This happened to my roomies Buick last week and it didn't turn a wheel till it thawed a bit and using the above measures keep battery fully charged as well, Good Luck..
