Back from the garage , He said it sounds like the diesel pump and that the pump should draw the fuel from the tank .
They are recovering the van next Tuesday / Wednesday.
Hi,
please do check with ignition on there is power to stop solenoid which is on injection pump .
If you find it does have power , switch off. Run a wire from battery positive touch the wire to the stop solenoid terminal - it should click(it is faint click) if it doesn't click then stop solenoid stuck or faulty.
With ignition off resistance check between stop solenoid terminal and ground - it should not be open circuit. A guess would under 20ohms.
Best wishes
Jack
