I had a kill switch like this on my 68 Camaro in high school. Completely different technology, I know, but the cool thing was that the kill switch was on a timer. So the car would start and run for about 30 seconds, then suddenly die. Unless you found the reset button, the car would crank and crank and crank, but never fire. Idea being that the guy might get it started, and get out into the street or whatever, but then he's dead in the middle of the road attracting all kinds of unwanted attention to himself. Seemed like a reasonable idea? Probably good enough to stop an amateur, but if a pro wants your car, he's gonna get your car.

Just remember if your tapping into the fuel pump, keep in mind whether you are tapping into the pump relays (probably the better way) or into the power leads to the pump itself. If you cut power to the relays, the wire gauge and associated switch could be very small and much easier to hide, versus cutting into the actual power leads to the pump which would require larger wire leaders and a bigger switch, making it slightly more difficult to hide.
