高压泵柱塞压力测试工具的方法：
A. 泄压:先拔下燃油泵保险丝、继电器或燃油泵插头，然后启动发动机，待发动机自行熄火后测量。B.安装燃油压力表:将燃油压力表与进油管串联，带测压口的车辆将燃油压力表与测压口连接。拆卸油管时，在油管接头下方放一块毛巾或棉布上。C压力表一般安装在汽油滤清器的出油口或燃油分配管的进油口。
完成上述准备工作，启动发动机，轻踏油门，观测压力由低到高过程，查看油泵在全负荷状态下是否出现渗漏问题。
Method of high pressure pump plunger pressure test tool:
A. Pressure relief: first unplug the fuel pump fuse, relay or fuel pump plug, then start the engine, and measure after the engine shuts down by itself. B. Install the fuel pressure gauge: connect the fuel pressure gauge in series with the oil inlet pipe, and connect the fuel pressure gauge with the pressure tap for vehicles with pressure taps. When removing the oil pipe, put a towel or cotton cloth under the oil pipe joint. C the pressure gauge is generally installed at the oil outlet of the gasoline filter or the oil inlet of the fuel distribution pipe.
Complete the above preparations, start the engine, lightly step on the accelerator, observe the process of pressure from low to high, and check whether the oil pump leaks under full load.
