    e320cdi Avantgarde estate 2001
    Hi , not sure if I'm in the right bit of the "tech" forum ,but here goes . Went out to the car about 30mins ago (e320cdi estate ) and put key in , started ,it ran for about 4-5 seconds and then cut out . Tried to re-start but nothing at all , just turning over and failing to fire up . One point I noticed was that if I released the key in the "starting" position , it did not return to "ignition on " position but kept starter going , and had to be turned back manually to "ignition on " position . Has anyone any ideas on this ? , I'm wondering if this is immobiliser related (??) .
    All help gratefully received ,and thanks in advance .
    Cheers
    Mike R

    sounds like you have a fuelling problem, either air in the lines or low fuel pressure.
    as for the key not returning, they are supposed to do this for a set period of time, by which time it would normally have started!

    Its normal for the starter to continue spinning until start is enabled. I would second fuel pipes letting air into the system. With a good battery and cranking she should restart.

    As above fuel pipes and o rings.

    When you start the car just turn the key and release...it will cancel itself when the car starts or has tried enough...it's not a problem.

    Update on this one . The RAC guy arrived in due course ,listened to my problem description and then went under the bonnet ,undid air intake hose clip , administered small quantity of "easy start" while I cranked it over and way she went ! . The car had been parked for a day and a half on a "nose-up" incline, and the RAC man had the theory that the car had suffered something he called "diesel run-back", apparently it can happen if the vehicle is parked in this way,it then causes an airlock in the fuel line , which has to be bled out in the above way .
    He then followed me on a five mile trip to next village , waited to see if car would re-start after visiting shop , all A-OK thankfully !! Result!!!.
    Something to bear in mind if you get a similar problem . The guys who responded here were certainly on the right track (fuel issue) ,thanks again .
    Cheers

    Changed all of the plastic lines on my 220 cdi about 2 years ago, all the ones on top of the engine anyway. Now as the weather is getting cooler it's taking longer for the engine to start when cold leading me to think that some of the pipework/seals that I didn't replace will now need doing. Are there any o rings around the fuel filter and the shut off valve assembly etc that I could usefully replace?

    cheers
