Bmw fuel pressure
Is fuel pressure supposed to climb with just key on?
Is fuel pressure supposed to hold after ?
My bmw doesn’t do either one.
It starts as soon as you hit proper fuel pressure,
just takes a few seconds to get there.
This Bmw has a fuel relay and separate fuel
Looking for advice.
Bmw prime fuel pump with driver door open . Do system scan . If I’m fact you really have n51 engine pull fuel pump out check for busted leaking hose off fuel pump. bmw will tel you must replace tank but can repair yourself.
