Default No communication from dlc. HELP!!!

I have a 01' Camaro SS and 2 weeks ago it was hard to start. Finally got it started and it bogged down very bad so I pulled over and couldn't get the car to start. Finally got it started and ran fine, but my tach didn't work. I drove it home and went out later to figure out whats wrong and the car fired right up and everything worked great including the tach. That night I got into my car and started it up just fine, but my tach, gas, and temp gauge are not working. Also my SES, service vehicle, abs inop, traction control off, and airbag lights are on. I went to Advance Auto to have it scanned and the scanner could not communicate with the car. I have searched the boards and found several people who have had this problem, but no one has posted how to fix it or what was actually the culprit. My fuses are all good, so I know that is not it. Can anyone give me some direction on how to go about finding and fixing the problem?????

The DLC port not getting any power at all usually means the CIG/ACCY fuse (inside the car) is blown - sure it's good?

You need the code(s) as a starting point. Did you check the port itself for b+ power?

I can't get any codes it will not communicate with the scanner. It does have power.
