I have a 98 c1500. I was having issues with passlock, I saw a video where if you can start it, you unplug the passlock while it's running and it will work without it after that. It did solve the issue, until I parked the pickup for 10 months, the battery was almost dead and now it won't start. Tried plugging passlock back in, but the security light has not turned on at all, so trying the relearn process has not helped. It is doing the usual start and stalls right away. Has anyone had the issue of security light not on and still not starting.
