Question type: Maintenance & Repair
The check engine light is on my 2003 GMC. The computer port inside the truck has no power to it. Is there a fuse on this circuit or was that optional equiptment on my base model truck? It has a 4.3L V6
There is a fuse and many times it is the cig. lighter (power port) fuse.
Thanks for your help. My cig lighter won't work either, so maybe that is the reason. Thanks again!
