I was just thinking about that today. Like a momentary switch nearby that you could use to cut fuel without waiting for the ECM to do it. Maybe use the switch to send power to a relay. Normally closed would connect the ECM to the fuel injectors as normal. Normally open would bypass the fuel injectors and substitute the appropriate resistor to mimic the injectors so hopefully it thinks the injectors are connected and wont throw a code.
Something else I was thinking about was if the fuel was cut manually, if you opened the throttle it might suck air through the engine easier and get you farther down the road without fuel.
On topic of the kill switch, I think the best idea is the wackiest thing you can come up with. Anything off the shelf, the thief will be more familiar with than you will. Maybe even something like a hidden fuel pump cutoff, so it looks normal when they break into the ignition switch, but when they go to start the car it cranks but wont run, and after awhile they will probably just think its a piece of junk and move on.
