I recently replaced intake gaskets and when I started the car, it threw a SES light. I checked it with my Actron reader and it showed missfires from where I got two plug wires swapped. I had to tear it down to the head gaskets and now I have a SES light again. BUt the problem is... my reader will not do anything when I plug it in. It won't even power on. I plugged it into my 01 GTP and my 01 SS and it powered up and functiond fine so it's not the scanner. Any idea what would keep it from getting power to connect? a fuse or something? It's just wierd that it worked fine once and then dow won't do anything and the car never even moved between attempts.
