We used to remove the crank fuse from my dads half ton so my step mother couldn't drive it just because he car was low on fuel. it'll crank til the battery dies or the wire burns off the starter but it wont start. you could also hide a toggle switch that controls power to the fuel pump, that's what I had done to my mustang
