I have an air-shut-off on my engine that is needed for pulling. It is inbetween the Intercooler and the Intake manifold. It is operated by a switch in the cab and when closed you can crank all day and nothing will happen! The only way to start the truck is to get out and pull the leaver and your good to go! I would think that them making tons of noise (cranking for 30 seconds) they would get the idea and screw off! If you pull the fuse they might sit there trying to find a kill switch for a while if there are no alarms going off or anything!
Just an idea
