Hi guys. I just got my OBDII reader in the mail today, and was eager to test it out. I plugged it in to my 2003 GT's OBDII port and . . . nothing. The lights on the unit didn't even light up. To check if I had just bought a knockoff Chinese piece of garbage, I tried it out on our '04 Silverado and my brother's '02 GTP. It worked like a charm both times. My research thus far has brought me to the conclusion that I have either a faulty fuse (the cig lighter one, perhaps?) or some ignition switch problem. I'm trying to find a fuse diagram and part online, and am not having any luck. Anybody had this problem? Any suggestions?
