Joe you have OBDI. If Google search Chevy ODB I eng service codes you will get generic codes. To retrieve codes you jumper A&B terminals with a paper clip and the eng service light on the dash will flash. If you see one long flash and two short flashes that would be code 12 and that means every thing is normal. If you see one long flash and 3 or more short flashes you have a problem. Is you service eng light on now?
