My civic has a check engine light but I have a huge problem the service port on the right when I put a paper clip into it the light doesn't flash to read me the CODES!!!!!!!!!!!!!! Its Not my only civic but I'm stumped on this one I have no idea where to check or if I can do it directly from the ECU Any help much appreciated

usually when you jump the pins and don't get codes its a sign of a bad ground or the computer dieing.

No I have 3 different ecu's and I tried them all in my hatch and there all fine The problem is the wiring I think.

There may be short in the service connector circuit. This would cause the CEL to stay ON. Check the BACKUP fuse under the hood, the relevant wires, and the connector itself for damage.
