fuel pressure 101:
here is the FPR chart I made using real Car real live data...
mostly all we car is the 0 vacuum data point, (means actual fuel pressure in PSI)
ignore BAR readings for ROTW, rest of the world metic.
0 vaccum 36psi, keyon, not started yet.
then idle., see that? a tad over 32psi.
this is all FPR actions here. the pump can do 60psi easy.
you may have bad FPR is all. if it does not do those 2 test correctly it is bad. (if the shunt pump test PAsses )
if you off the vacuum nipple here and it leaks fuel the FPR IS BAD>
