(I change my by pass solinoid valve 2days bfore it happened first time)

At those temperatures, the battery may have frozen. You may want to have it tested and/or replaced. Also, start using 5W-30 full-synthetic engine oil--it will definitely help your car start better in cold weather:

Look into Mobil 1, Pennzoil Platinum, Quaker State Synthetic, or Amsoil--you'll be glad you did.
