I want know how to remove the theft control module, because after completing all the youtubes * recommendations on resetting the the computer, nothing has worked except adding a resistor to the ignition module,now it starts but doesn't stay running, is it doable taking out the theft module without screwing anything else up, I know I won't have any security but its ok, I just want it to stay running

What lights are on when it quits running?

What engine does it have?

Tahoe steering was replaced. I've tried resetting the computer.ive put in a resistor and the truck started but won't stay running. The security lights still on

The security light stays on, the engine is the 5.3 vortec

It may be bricked. Do you have a scan tool that can look at live data?
