good day friends i am new to this forum so please forgive me if I have posted in the wrong place. i have a 2001 e46 320d m47 prefacelift and it has a problem of not starting. it cranks fine but just wont start. I have run a diagnostic and it gives me 2 fault codes with communication to the injection pump. has anyone had the same or similar problem or if you could plz advice me as to what to look at next. any assistance will be greatly appreciated.
Hey bud
Welcome to the fanatics. You can maybe start a new thread on the topic, but in the meantime check the advice given above about listening if the lift pump is making any sound when you turn the key to position 2 (just before start), if not check the relay of pump.(in the glove compartment behind the fuses. Should be the third one from the left, but I'm not 100% sure. (Green in colour I think. Change it with one of a similar colour and listen for pump again.)
this model has no lift pump.. it still uses a high pressure fuel distributor pump, a Bosch vp44.this is different from the common rail engines high pressure pump, the vp44 also distributes and times the diesel injected, so the injectors are mechanical.
the fault codes you got points to the controller mounted on top of the pump being faulty, or the wiring going to the pump being faulty.. unfortunately it could also mean that the pump has mechanically failed, not uncommon on this specific pump. expensive to repair or replace , and definitively not diy unless you really know your stuff..
