A vehicle theft prevention system is disclosed comprising a detector which alerts the system to a change in driver of the vehicle and which is connected within the existing electrical system of the vehicle. The system also comprises a reset switch which must be pressed within a predetermined time period after a new driver enters the vehicle and assumes the driving position to disarm the system. Failure to disarm the system results in the gradual diminution of power to the engine of the vehicle after said vehicle is driven away, preferably by reducing the electrical current supplied to or voltage applied to the electrical fuel pump of the vehicle. The system is ideally hard-wired into the existing electrical system of the vehicle, and optionally the electrical circuits of the vehicle which supply power to the horn and/or external indicator lights or brake lights. In this manner, as the vehicle slows as its power is diminished, an audible and/or visible alarm signal can be provided to draw attention to the possibility that the vehicle is being stolen.
