Need some help... OBD2 port isn't powering up?

took the T/A and got to see the boost gauge in action (digital).

1st gear - as soon as I hit 0psi the tires break loose.
2nd gear - as soon as i hit 1psi, the tires break loose
3rd gear - as soon as i hit 5psi the tires break loose
4th gear - I hit about 8psi around 4500rpm and i got off it because it is too fast for public backroads.

The one problem i have is my OBD port on the car isn't powered up. I hooked up an OBD2 scanner (which blinks if there are no codes), and it never turned on. this is why i can't get my tunercats to read. any ideas?

Check the fuse for the port. It's on the same circuit as the cig lighter.
