My truck does not have any spark to the ignition.
Lack of spark to the ignition system on your GMC Sonoma can be caused by a variety of components. These possibilities range from the ignition control module failing or not receiving proper battery voltage, to a faulty ignition switch and bad crankshaft position sensor. Due to this wide spectrum of possibilities, I would recommend enlisting the assistance of a certified mechanic to come by and diagnose why your Sonoma has no spark. They will have the experience and tools needed to determine exactly why there is a no spark condition as well as make the repairs necessary to get your GMC running again quickly.
