The check engine light came on so I stopped into Auto Zone to get the codes read. After the guy hooked up the scanner and turned the switch on he said there was no power at the diagnostic port so the scanner wouldn't work. Is there a fuse for this port? Where do I need to be looking to find the problem? I tried cycling the ign. switch 3 times to read the codes through the odometer but that didn't work either. I did get the gauge cluster test to run by pushing the trip odometer and turning the ign. switch on, that checked out ok. Thanks.

 

Yep there is. Gonna have to take a test light and with the key on prob all the fuses till you find the bad one
