5.4 2001 F150 Hard to Start
#3
hard start at times
sometimes everyday, than sometimes it won't be run for a couple of days, changed the pump this past summer pressure was 30psi now its 40 seems to have helped some changed filter all so my mech and I are thinking about the fuel reg.

The regulator has a check valve in it or there is one in-line. If the check valve is bad, you will loose the static pressure in the line and it will take the pump much longer to build the line pressure up to where the fuel is pumping through the injectors.
