三菱车辆电气系统，Oulander Motor4G64模型2003 V. Amer

I have problems with the fuel pump, it is not all the time blocks the 24V signal at that time I have no indication of the light of (Chek ing) Failure indicator, but it does not start due to lack of fuel, I take out the pump and try it out of the tank and it works, I install it again and start without problems at 22 days it gives me the fault again, the pascon (filtering) of clean pump, clean tank.
如果有人有这个错，请帮忙。
