long story short - a second hand throttle body, new low pressure pump, new high pressure pump, and 3 second hand injectors later it (TD4) actually runs again, however still the same problem as before it stopped. every now and then when you pull up to a stop the tick over will climb or settle i suppose at about 900 rpm - the ecu must do its thing then it will drop to 500 or less - it hasnt stalled since i got it back but has done before the work.
has anyone seen this carry on before? i did put injector cleaner through it with no difference now there is 3 different injectors in it with no difference...
ill go back and update my other open post now

Only when the vehicle in question was entirely out of fuel.
Did you keep the old injectors? Are the new ones clean? I'd be doing a leak off test comparing all the units before considering anything else.

thanks for the reply - i have 2 of the old ones - the new ones i got were like new coming from JJ car parts.
out of fuel hmm air leak maybe? I think you are right i would need to test them.. could be a while
