OK i live in iowa and its freezing cold right now, and only when its really cold, like below 0 my car wont start... The battery is fine, i am getting plenty of power to it. Everything comes on, like the radio and lights but it wont even turn over when its cold, just turn the key and nothing... Any suggestions of what is wrong? I was thinking either spark plugs or starter? But i am thrown off cause it only does it when its really cold.. Thanks for the help!!
