No !!...........The check
valve is located in the inlet to the pump and will hold regulated pressure
indefinately or until relieved by leaky injectors or
the afore mentioned bypass sysrem.........

Ernest,
Your EFI fuel pumps have a check valve
in them and will hold regulated pressure
for a long time or until leaky injectors relieve this
pressure..........Short of replacing
the injectors the fix is to put a pressure relief orifice from the
fuel pressure line to
the fuel return
line...
Shouldn't shutting down by
cutting power to the fuel pump relieve the pressure,
though?
