I have a 03 g35 coupe. My problem right now is that the fans would go on during ignition mode, and it can't start which I'm assuming because of the red security light that is on when trying to crank. Also, my obd2 port doesn't get power so I can't check what codes I have. Any second thoughts that you guys would have? Also here is the video I was watching that had the same symptoms as me but its an older G35.

 

Did you ever figure out the issie with the no power on the obd port?
