This invention provides a simple means to initiate the movement of a vehicle by utilizing a fuel injector system, which determines a length of a magnet on the flywheel or crankshaft pulley. This system enables a person to choose a speed where fuel from a fuel injector can be efficiently dispersed into an engine. The engine's fuel efficiency is optimized by this invention, because only a specific amount of fuel will be dispersed to generate electricity to operate the engine, which prevents the engine from needlessly expending energy.
