Ok so 2 weeks ago I tuned my car for 93 with my diablo tuner. My CEL came on last night went to scan and nothing, no power. I plugged it in to the wall adapter when I got home and sure enough it fired right up. I had to run a cord to my car so I could scan and clear the code. I looked online n saw that it's most likely the fuse when I checked ever fuse from the cig lighter to the port fuse they all check out what could this be?
