The device i.e. electronic control unit (ECU) (60), has a detection value procurement portion for procurement of a detected value of a fuel pressure in a low-pressure region between a feed pump (12) and a high pressure pump (20) or for procurement of a detected value of a physical variable that is related to low pressure. A determining section determines whether a pumping promotion anomaly of the high pressure pump is present based on the detected value. A pumping delivery rate estimate portion estimates a pumping delivery rate of the high pressure pump based to the detected value. An independent claim is also included for a fuel injection system. |
