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?

Check to see if you are getting spark and fuel to the engine. If it won't start, one will be missing. Refer to our homepage under the DIY section for direction for checking both. Once you determine which is missing, then you know what circuit or system to attack.
