Moseying along happily and it cut out.

Its got spark, fuel, fuel pressure at the injectors, timing and valves move.
Where do I look next? Oh, Ive changed the ECU, swopped relays around. No difference.

God I love Diesels!

Hi,

Firstly I would check the lead from negative side of coil to ECU. Should this be disconnected somehow, the engine will not run. It tells the ECU about the engine rpm's.

You can also by-pass the overrun-fuel-cut-off-relay, throuh which this lead goes. This relay or the valve that runs it may be faulty.

Just a thought,
