Extract from a Renault training program.
>>> • The first high pressure test consists of verifying the natural potential of the high pressure pump. This refers to its ability to pump fuel under pressure.
Input flow control type
Disconnect the fuel flow actuator and inhibit engine start (use command mode or disconnect the injectors). Note the pressure value when the starter kicks in. (In fact, the actuator is open when it is resting. Thus, the pump operates to its full capacity.)
The pressure value must be greater than 1050 bar for a K9K engine, and greater than 800 bar for an F9 or G9 engine. (Minimum speed with the starter engaged in compliance with requirements specified in the documentation). <<<

PS. Have you looked at the leakback quantities?
