does the truck start and run?

 

I assume you pulled all the correct fuses when you programmed it right? Try disconnecting the batteries for 15 mintues...

I got it to working now. It only shows to pull one fuse and that is the onstar fuse. I do not know what the deal was but I just let the truck set for about 2 hours and wnet back out and tried it again and it worked just fine.
