2003 Trailblazer, 6cyl, My won't start when the temperature outside gets below 30-35 degrees. When the temperature is warmer is starts right away. Check engine light comes on when it does start and after the second or third start goes off. Have taken to local shop and they say the codes are not common and seem to think it is in the wiring. The temperature has been under 30 degrees for a week now and will not start now. What is wrong?
