| description | PROBLEM TO BE SOLVED: To provide a checking system capable of checking an operation status of an injector while the making work environment good. SOLUTION: In the checking system for an engine checking the engine provided with the injector 5 injecting fuel fed through a fuel feeding passage and a control means operating the injector 5 at a fuel feed timing established beforehand with rotation of a crank shaft 2, a electric motor M rotationally driving the crank shaft, an air supply device 9 supplying air to to set inside pressure of the fuel feeding passage 4 at an established pressure, a pressure sensor 10 detecting inner pressure of the fuel feeding passage 4, and a test distinguishing device 11 distinguishing an operating status of the injector 5 based on detected information of the pressure sensor 10 under a condition that the crankshaft 2 is rotationally driven by the electric motor M.
