Well I had read somewhere that a guy had his 99 Civic stolen from his drive way. He had a Alarm, Fuel Cut off switch, ECU take out of the car, and main relay pulled. Car was still stolen. I believe anything is possible, and I don't expect anyone here to be experts a thievery. I know thieves can bypass alarms, eaisly, but how can they bypass the fuel cut off? Won't the car not start if the ECU is pulled? Or if the main relay was pulled? I kinda think its an insurance fraud job or someone who knew the guy. I just don't understand how a car can start without an ECU. Can anyone explain? I just want to know for my own security that way I can try to improve on what I can do so my car is not the next one to end up missing, becuase its not fun, I had one gone before.
