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!!! :)

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?
will need more information, how strong is the battery? have you remover the air cleaner, to check air flow, to run you have to have oxygen fuel and spark, all in the proper portions, Winter temps can often cause paper air cleaners to absorb moisture, then freezing temps, block airflow. what type of fuel system, efi, or carb throttle body are we talking about? Carb or throttle body you can introduce a few drops of fuel in the top (caution do not use much a teaspoon or so from a small open container as vapor is explosive!
What is engine size? Use a gage and check proper fuel pressure. My info says 41--47 psi, 5.7L engine.
Can you park on level ground to do testing? Visually check for spark at the plugs. Can you check if system is running rich or lean? How long since overall tune-up?
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
