Not all cars systems have the fuel pump priming at initial ignition on. He fuel pump would run onces you start cranking as it uses the starting signal to control the circuit opening relay which is part of the fuel pump circuit.
However there is a problem with the fuel pressure. At idling and vacuum applied to fuel pressure regulator, the reading should be 30-37 psi.
Without vacuum the pressure should be 38-46 psi. Check the pressure again and disconnect the fuel pressure regulator vacuum hose to test if the pressure increases.
If it is lower than expected, clamp the return hose and note if pressure increases.
