				ODB dead
			 
			 
			
		
		
		just tried to get an inspection sticker for my 2007 GM Envoy. 
 
garage said they plugged into the OBD port and it was dead; so they gave me a rejection sticker.  
 
maybe a blown fuse or wiring issue? any experience with this? trying to avoid some getting slammed at the dealer for a few hundred if it's an easy fix.
