Hi. I'm new over of Voyager 2.8 CRD and I have the same problem recently. I checked that valve and petrol was going not from that place only from fuel line pulled out from it. As engine starts only when I put key in to ignition and start without waiting for glow plugs to warm up. Today on the way to work engine stops and it was a bit scary as I was overtaking a lorry on 3th lane. This my be the same problem?
