Does the 1993 Ranger 3.0L V6 have a fuel prime when you turn key on?

I have a fuel problem with a no-start. Replaced fuel pump and new gas.
For Key on Engine off, I have 40 psi pressure on fuel rail - stays at 40 psi (there appears to be no timeout on fuel pump (2 to 3 seconds like some cars) - key off results in pressure bleeding off to 0 within a minute.

Seems strange to me....pressure bleeding off may be injectors, but prime?
