What is the factory specification for fuel psi? Am I correct in thinking the Fuel Pump Driver Module pulse modulates voltage to the fuel pump? Is it more common for a fuel pump to fail opposed to the driver module?

this cold be a tossup I've seen both fail but not at same time. 55psi is what it should be with key off engine running. for module if you scan it that should show that.
