Can't get it to start. New battery. All electrics are good. Suspect anti theft logic is not letting car start. Seat heaters do on work. Checked ign.3 fuse and it was good.

JA: Are you fixing your Yukon Denali yourself? What have you tried so far?

Hi there, I am Cam. With your Yukon, when you turn the key on, does the check engine light on?

Is the security light flashing?
