I had this problem last winter, but was usually when it was way below zero. I changed the spark plugs and didnt have the problem the rest of last winter, also there is a new starter(aug 08). Now the past two morning, the nights have gotten down to about 35 degrees here in Illinois and now it wont start. It sounds like its out of gas. Yesterday we left the hood open for a little in sun and then it started and continued to start the rest of the day and night. Now again today, back to the same thing, wont start. HELP ME!!! :)

Since batteries lose almost half their cranking power at freezing, and since diesels require much higher fuel temps to start than gasoline engines, many recommend using a block heater whenever the temperature is under 35-40 degrees if starting becomes a problem.
When was the last time you changed or cleaned the spark plugs. I had an older car and just would not fire up when it was real cold outside. We ran down two batteries so at zero degrees Fahrenheit I changed the spark plugs. No problem after that
also is your carburetor set up so the choke is working properly?
Check the engine temperature sensor. There should be two of them, one that reports it inside of the car and one that reports it to the ECU. The one that reports it to the ECU has likely failed and needs to be replaced.
White smoke could be as simple as condensation in exhaust from sitting overnight. I'd be more concerned if white smoke continued when warmed up.
The "miss" could be a bunch of things... When was last "healthy" tune up? Plugs, wires, ALL filters including fuel filter? I would start there, makes a good "ground zero" reference point and see if miss is still evident. You might also consider running a good fuel system cleaner w/next tank full of gas. Especially in winter months when temps fluctuate, condensation forms in tank. (water) Spark plugs & water don't get along well.
if you have a no spark scenario i would check your crank sensor located at the top left side of the harmonic balance pulley.the crankshaft (about 11'oclock) a 2 wire plug with a sensor on it check to see if it is damaged or unsecured. this sensor can cause no spark if not working correctly. This sensor is based of frequency not voltage testing is difficult, just make sure that there isnt too muck air gap. and that it is secured.Lastly may want to check timing possible that the belt has jumped some teeth and she has fallen out of timing. maybe a bad tensioner The coil will adapt i think up to 10 degree, ****** or advance. Good luck
change the spark plugs,after they sit in cold and you warm them up to 45 degrees or whatever and you try to start the car the spark is just hot enough to ruin them,especially if they havn't been changed lately and theres a lot of miloes on them
