Your suggested fix worked!!!
I too was having starting problems, apparently due to the passlock. My truck which is a 2006 Colorado, 4cyl, 5 spd, would randomly not start. After waiting 10 minutes it finally would start. I started to search the internet and ran across this post. As I read over it, I kept thinking, "this is too simple, too easy. What is the catch? Does this guy know what he is talking about?" Well come to find out he does!! After much hand wringing, I snipped the wire. My truck has not failed to start since. Yes, your light does glow on the dashboard but hey, that is better than a several hundred dollar trip to the dealer.
One final thing. Where do you find the LED mod how to?
Noximus, thanks for your fix!!!
