2002 Chevy Suburban 2002 Suburban not starting

I have a 2002 suburban not starting. We have never had any problems with this vehicle. Drove it around at midnight a couple of days ago. Tried to start it around 815 am. The temperture dropped to about 15 degrees that night. The battery is fully charged. The engine does not even try to crank. It will not take a jump from another vehicle. I do not hear the fuel pump come on, then again Ive never noticed if it ever did. I have a 2000 montana that you can hear the fuel pump. There is about a half a tank of gas. Checked the relays in the fuse box under the hood. Checked all the fuses that have to do with ignition or starting the vehicle. Banged on the starter with a hammer. Made sure the Pass-lock system was not activated. The security light does not flash continually, it only flashes when you first get in. Checked to see if I had any error codes, I have none. Out of ideas. The boss is on my back and refues to cook dinner until this is taken care of. And Im hungry.
