I purchased a pcm tune online and went to install it. When I tried to crank it over nothing happens. I tried to do the security relearn but the light never blinks of goes off after 11 minutes. Just stays on solid. Then I read the forum about cutting the blue and white white to disable it and got myself into an even bigger mess. I have to go to work Monday so any advice is greatly appreciated. Its an 04 colorado base model 3.5l i5 rwd.
