2002 Tahoe starts and then dies
I'm working on an 02 for a friend of mine and he said after replacing the battery it started doing this. The only code I find is a 1626. I put a new GM ignition switch in it and nothing changed. The security light also stays on even when the key is removed. Also the automatic head lamps dont come on when you turn the key on but you can turn them on manually. The dome lights dont work and neither does the remote. Has anyone ever experienced this? I have read a lot and watched a lot of things but nothing covers what issues I am having.

You need to do a passlock reset. Plenty of info and videos out there on the procedure.

Re: 2002 Tahoe starts and then dies
To reset Your 2002 Chevy Silverado security system put the key in the ignition, turn the key to the on position, and leave it on until the security light goes out.
Usually abut 15 mins. Once this happens crank the truck without turning the key backward, just turn to start. This will reprogRam the transponder from the ignition switch. To prevent someone from using a fake or non-registered key, GM installed an anti-theft system called Passlock. When the wrong key or other tool is used to crank the ignition, the Passlock system disables the truck's fuel system. :chevy::chevy::chevy: |

That procedure doesn't work, I haven't done anything with it for a while and am still looking for an answer.

The answer is that the security system is malfunctioning. I had to defeat it on mine.
