The invention discloses an advanced pressure buildup method for an automobile oil pump. The method comprises the following steps: an automobile body controller judges the starting intention of a driver, then the automobile body controller outputs a low-level signal to a first oil pump relay, the first oil pump relay works, power is provided for an oil pump motor, the oil pump motor continuously works to perform pressure buildup on an oil pipe, and after the oil pump motor finishes the pressure buildup of the oil pipe, the first oil pump relay stops working, and the oil pump motor also stops working. According to the method, pressure buildup is realized before the driver shifts to the ON gear, so that engine starting failure or longer starting time caused by low oil pressure of the oil pipe is avoided.
