OBD2 port not working

Emissions station tester said they could not run the test since no link to the OBD2 connector.
I went to Track Auto and used there scanner and I got the same problem...no connection.

Edjack,
I checked Multi-information Display 25,55; I also checked Diagnosis plug 15,38;
and On board Monitor 43, 56, 58 ... All fuses were good.
So bad connector or broken wires somewhere ? what do you think?
Thanks,
David

Don't know what year your car is... If you have the round OBD connector under the hood on the passenger side, make sure its cap is installed and making good contact.
I had it once when I was trying to connect to the car using the rectangular one while the round cap was removed, I could not get the connection to work.

Cleaned and tightened the roound cap ....It worked ! I did have a communication between the diagnostic tool and the car at ODB2 port.
Many Thanks to Flug540, Edjack and the Forums.
