2006 GMC Envoy denali wont start

[sdkksk]

Hello all. My denali will not start when I turn the key. Everything lights up and everyting works, radio, windows, etc... I do hear a clicking sound coming from the fuse panel under the rear seat. Can anyone help?

Welcome to AF, from here very difficult, we can assume it is in park of course. Does the security lite on the dash stay on?

Thanks for the reply. It is in park. All lights clear but does not attempt to start. Acts like when you have a car in gear and try to start but the car is in park. The only thing I hear when I turn the key is a clicking sound form one of the fuses in that are located under the passenger seat. I traced the fuse and it is the "Retained Accessory Power" fuse. If this fuse is bad would it stop the car from starting?

No, this is for the operation of the interior lites after shut down, this could be a starter problem, a starter relay, ign switch. Don't know if you have the tools or know how here, you may need some help on site with this. Aftermarket alarm, or theft deterrent system?
