I agree with Andrew (of course!). Some diesel engines, especially the older models, do need bleeding at the pump and then at the injectors.
I've just one thing to add -- assuming the filter is the replaceable-element type, are you certain that you put the seals back in the right place when you changed it? On some filters the upper and lower seals (one flat and one cone-shaped)can be fitted about face and shut off the fuel supply. In this situation, I believe that hand-priming can force a bit of fuel through but the engine can't produce enough flow by itself for running.

'assuming the filter is the replaceable-element type'
yes
'are you certain that you put the seals back in the right place when you changed it?

ah ha that sounds like a good idea i'll give it a try. Its small things like this i really have no clue about.

'Just to add my sixpen'orth. Try this, loosen banjo bolt at the pump where the pipe from the filter arrives and prime till air bubbles stop,tighten, then open the injector unions and crank on full throttle until fuel leaks out....'
I tried that and no fuel would come out of the banjo bolt, but fuel is definately going into the injection pump. I can unbolt the fuel input pipe and prime and it comes through.
Does this point to a bad injection pump ?
'The other possibility is that you may not have run out of fuel in the first place and the pump has indeed failed'
It definately ran out of fuel i live way out in the country and misjudged the amout in the tank vs distance to nearest filling station.
I'll try changing the solenoid, check for leaks again, change the hand pump, check the IP belt, check the compression, change the air-filter. But i still have a feeling that none of these things will get it going. So does that only leave the IP ?
thanks !!

Hi and thanks !
It turned out that the glow plugs had gone as well as the hand pump. The car is now running again !

Probably the continued cranking finished off a set of well-worn glow-plugs.Had the same on a gasoline motor;the failure of the idle fuel cut-off solenoid and then the repeated cranking finished off the coil-12 v. thro the 8 v. coil.
