Without the engine running your intake manifold will be at atmospheric pressure.  Atmospheric pressure is 100 kPa at sea level at such and such a temperature.  When you start your engine vacuum will build and the manifold pressure will drop to something less than atmospheric.

You can do it cranking with the injectors off and/or with it idling
