OBD2 Not Working

I have been have continous issues with my 98 z28...wasnt starting found out it was just a ground wire was broke. Now I am driving the vehicle and the service engine soon light came on. Figured I would just go to Autozone and get it checked...the code reader does not recognize the computer. I have not done much troubleshooting with PCMs before this past week so I have no clue what it is. Any help is greatly appreciated....Again

See if the CIG/ACCY fuse inside the car is blown, it also powers the DLC port.

Should be the fuse, did it blow immediately? If you have a meter check for power at the port: www.obdii.com/connector.html

The fuse blew when the moron at autozone plugged in his scanner...guess it was shorted out, replaced the fuse, have a friend with a scanner and tada!!! it works. I appreciate your guys input, This car is going to end up driving me to the nut house soon.
