    The hardest point of this post is going to be able to explain this noise, so My crafter is a 2008 with 112k miles, owned for 3 years which had cam belt and dpf cleaned, all running ok when had power drop off on acceleration found the exaust blocked so renewed it, but then this noise happened, when cold and the revs hit 1800 rpm there is a crack sound like a branch breaking and the power shoots up to normal, i forgot to mention that under 1800 it seems slugish, vanes on turbo are free as is actuator, egr working as is throttle flap, no fairy lights on dash either, it is the sound that is most disturbing because before the crack happens there is also a background noise of like a build up of preassure also you could also explain it as sounding like a tight belt or a high torsion sound, it really is worrying, talked to some locall garages but none could explain it apart from the obvious of turbo which i find hard to believe at the moment, as when the crack happens the engine faulters slightly then goes off.
    I told you it would be hard to explain so any help would be very gratefull.
    Brom.

    Hi, back again, 40 lookers but no replys, just guess i didnt explain the noise clear enough,
    New events happened over last 8 days, on first start in morning engine starts for about 3 seconds then stops try starting but just turns over with a little partial ignition a s if one cylinder partially fires, this can go on for about 10 trys and luckily it starts and runs. My intuition is its fuel pump related in some way, and this was the hold back and then the crack noise of engine firing at proper injection pressure.
    Has any one had similar problems with fuel pressure.
    Hope this opens the problem more.
    Brom.
