my neighbor has the 2002 yukon. he has the security light stuck on and it starts for a second and then shuts off. he did the turn the key for 30 min and the key for 10 then 5 seconds for the 3 times and i forget the other one. so outside of draggin this to the dealer to have them do some bypass i'm wondering if there is a bypass i can help him out with if for nothing else but to get it running to prove out nothing else is going on as they all think. on my s10 i found some threads on the s10 forums that talked of just bypassing it completely so if that can be done to this truck they may just want that done and be done with it. thanks
