Help - went to drive home today and my truck will not start. It is a '03 Quad cab 4x4 w/ auto. I had just returned from a trip where I bought fuel at several different places. The truck just turns over and will not start. The temp today is 16 degrees, very windy and cold. I think I must have water somewhere but not sure what to do. Truck has always started in weather this cold and colder. Any help on where to start would be greatly appreciated.
