Fault of the built-in oil pump in the high-speed pump of Beijing Aerospace

After the auxiliary oil pump started, the oil pressure was 2.7 kilograms. When the pump was turned manually, the pressure remained unchanged during normal operation; however, it rose to 4.5 kilograms when the pump was turned in the reverse direction. When the pump is started, the oil pressure drops instantly, and the pump stops due to interlock (at this time, the auxiliary oil pump continues to operate). It happened the same way several times in a row. What is the reason?

Is the check valve in the outlet pipeline of the auxiliary oil pump damaged?

Is the oil pump motor running in reverse? It’s best to send a scammer to see what they look like. To facilitate discussion.
