Abstract
Upon receiving a request to stop an internal combustion engine, processing circuitry of a fuel supply device opens a relief valve by increasing a fuel pressure in a delivery pipe to a specified pressure or greater before stopping the internal combustion engine. The processing circuitry determines whether a fuel pressure sensor is normal based on a result of comparison between a fuel pressure in the delivery pipe detected by the fuel pressure sensor and a fuel pressure determination value after the fuel pressure in the delivery pipe starts to decrease as a result of opening the relief valve.
