What&#39;s up No power--as in when you plug in a scanner or programmer? Are you sure the scanner/programmer works and has batteries? Call a parts or service tech at a dealership and try to see if there is a specific fuse or replay that controls the OBD-II port...

Used to be it was the cigarette lighter fuse that powered the OBD port.

the scanner is a brand new snap-on scanner lol.. and i also tried a superchips. the scanner says it has no connection and the superchips wont even power up... im gonna try calling a dealer today. something this stupid really makes me feel like an idiot. thanks for the replys ill let ya know what was up.. any other suggestions are welcome

thanks

i had that same problem at one time..... after an ASSLOAD of money i spent on other things that all went wrong at once......

a stealership changed out the whole fuse junction box underneath the hood and everything worked fine.....

so i would check a specific fuse in that box

correct, it is powered through the cig fuse, which is in the fuse block under the hood.
On the obd2 port, pin # 16 is battery positive voltage, orange wire
pin # 4 black & 5bk/wh are grounds

Well, with that said, go check the fuse. If that isn&#39;t the culprit, then get the test light out and see if those pins are working...
