A common fault showing up on many diesel vehicles of this era, is caused by a fault in the electronic control unit mounted on the fuel pump.
The pump in question is the Bosch / Cummins VP44 or VP30 (type PSG5), and the symptom is that the vehicle will not start, or it fails to re-start after cutting out.
Typical fault codes recorded are P1551 / P1561 / P1630 / P1631 / P1651 / P1661
If your vehicle has other issues such as poor running, loss of power, excess smoke from the exhaust etc, then this service is NOT for you.
Inside the electronic module (the EDU / ECU), is an electronic circuit that controls the fuel pump operation.
The problem is that the main transistor relies on fuel flow through the pump to keep itself cool.
Sometimes this can be intermittent, (eg on over-run). so the transistor gets too hot and eventually fails permanently, resulting in no fuel delivery, and no start.
This can be confirmed by checking for fault codes P1551 / P1561 / P1630 / P1631 / P1651 / P1661.
Of course, there can be other reasons for non-starting, including other (mechanical) parts of the pump, but this is a very common cause, and the only alternative if you have eliminated everything else
