The invention discloses a fault diagnosis method, device and equipment for a fuel system and a medium, and the method comprises the steps: obtaining the parameter data of candidate working parameters when the fuel system is in a working state, and generating a candidate data matrix; determining a target working parameter from the candidate working parameters based on the candidate data matrix, and generating a target data matrix based on parameter data of the target working parameter; and inputting the target data matrix into a fault diagnosis model, and performing fault diagnosis on the fuel system. According to the technical scheme, the fault symptoms of the fuel system can be effectively recognized and judged, so that normal operation of the fuel system is ensured. 本发明公开了一种燃油系统的故障诊断方法、装置、设备及介质，该燃油系统的故障诊断方法，包括：获取燃油系统处于工作状态时的候选工作参数的参数数据，生成候选数据矩阵；基于候选数据矩阵，从候选工作参数中确定目标工作参数，并基于目标工作参数的参数数据生成目标数据矩阵；将目标数据矩阵输入至故障诊断模型，对燃油系统进行故障诊断。通过上述技术方案，能够对燃油系统的故障征兆进行有效识别和判断，以确保燃油系统的正常运行。
