PROBLEM TO BE SOLVED: To provide an abnormality detection device that determines as accurately as possible a non-ignited state in cylinder and provide a fuel-injection system using the same. SOLUTION: If an ignition determination condition is established after completion of start-up of an engine, whether or not there is a cylinder not ignited is determined from fluctuation of engine speed. In the case of non-ignition in a cylinder, the member of increase in engine rotation is made smaller than a predetermined value. If there is a non-ignited cylinder, common rail pressure of the non-ignited cylinder is acquired, whether or not proper pressure change is present is determined. If the amount of reduced pressure of the common rail pressure is not within a proper range, it is determined that fuel injection valve is not injecting properly. In a non-ignited cylinder, a non-ignited state is determined by determining whether or not a fuel injection cylinder is injecting properly, and then appropriate measure is taken.
