I have a 95 z28 with obd 2. The car runs fine,no check engine lite. But when i plug in the auto xray its not receiving any information.xray says to check patch cord connection.Any help here would be appreciated thanks kevin

 

Your 95 is an OBDI with an OBDII connector. You need to use an OBDI scantool.
