Did it scan, but just not show an error code? Or was the scanner unable to establish a connection with the computer? If it was unable to establish a connection, check to make sure you don't have a burnt out fuse for your cigarette lighter/power socket. Some GM cars (Chevy included) use that same circuit to power the OBD diagnostic port.

 

It didn't get a reading at all. So i'll have to check that.

Any clue about the front bumper?. I want to get one like that in that link..

 

you may have already read my PM, but if not, the bumper looks like a Xenon bumper to me.. I PM'd you with a link
