I was thinking of buying a Chevy so I had it checked out by Firestone...... mechanically it was fine, but when the tech. tried to read the scanner for codes he said nothing came back........ the check engine light never comes on but all the other cluster lights work fine...... I'm wondering if the seller unscrewed the check engine bulb, but I don't understand why the scanner is not able to read anything... if the PCM was bad would the truck even run as good as it does? What are the possible reasons for no feedback to the scanner?
