no power to diagnostic port

I have an 02 chevy trailblazer which is giving the check engine light and reduced engine power signal.
I plugged in my obd2 scanner and nothing. the fuses and connections are good. Any other ideas?

you might take some non conductive contact cleaner to the port, clean it.
