Wonder if anyone has any ideas about the following problem:

98 Elite 2.5td Changed glo-plugs, now starts after half turn of the starter motor and will tick over forever thereafter but immediately the accelerator is pressed it dies.

It is with a local agricultural engineers who are normally excellent at finding solutions even with weird and wonderful kit which no one else understands. They have changed the glo-plugs previously with no problems, in this instance they are completely stumped.

They cannot read from the obd port.

The only other fault which happened months prior to this and previously had no impact on the engine function is the fuse controlling the heater blowers and power steerling etc. keeps blowing.

Any ideas to try gratefully received.

Might be worth trying the paperclip trick, to see if you can get any error codes.

It's a BMW lump.

Sounds like there's not enough fuel getting through.

Does it have a separate fuel pump in the tank?

Fuel pressure to the mechanical pump and to the injectors would be a starting point.

If the two numbers are similar then the mechanical pump would be one culprit. Fuel pressure regulator being the other. If it's returning most of the fuel to the tank, then it will be under fueling as the throttle is pressed.

I have it in my mind that these engines dont care so much if the tank pump is working or not.  Fairly sure thats the case with many non common rail diesels.  And the fact it idles...

OP - they had no reason to, but do you know if they removed the fuel pipes?  If so, might need bleeding on all 6.
