So latest update:

Have put stethoscope on the injectors and can't hear clicking.

Cracked injector pipes to bleed as specificed and whilst it does bleed out air and fuel appears, its not what I'd call high pressure...

Well it won’t be high pressure when you bleed like that, this is to confirm fuel is reaching injectors

If you now tighten everything up, just leave one injector nut loose and try the starting regime again.
Jumper leads on a running donor car.

Thanks for the advice but still won't go. I can see air STILL coming in through the clear sections of pipe near the filter so I can only presume we've got a leak somewhere. You'd think deisel would be leaking OUT when its left though.

Just read your original post

Assuming you checked the fuel tank to see it's ONLY got diesel in it!

He never split any pipes underneath while fording the jagged stones river!

About 100 years ago I struggled for ages working on my old Dodge wagon before realising the stack pipe on the fuel tank
was rusted half way down and sucking in air when the tank got to half full.

I did get it home by tying a 5 gallon drum of diesel on the passenger seat, higher than the engine, then syphoning a tube
direct into the pump feed.......gravity feed......you can't beat it!

Did the same trick in the early seventies in Iran, miles from anywhere after a ruptured fuel tank, drum on the roof rack of my Scania....gravity feed .................

CHECK THE FUEL SOURCE
if needs be, a seperate tank, but fill the filter first.


Try filling the fuel filter manually then seeing if it runs, even for a minute.

Yes my first thought on the fuel being part water but all looks good.

Someone suggested the supply and return pipes being on the wrong way around (which would explain the air) but they are moulded fittings so think that would be hard to do.

Will have another look underneath but would have thought Deisel would be coming out where the air was getting in.

See my edited post

Try filling the fuel filter manually through the inlet hole

An excellent trouble shooting tip!

Yes done that, we think we might have a duff injector which is stuck open and leaking air back into the system maybe?

That's why I asked did you hear it running.

Over the years I've learned to distrust everyone!
Unless I heard it running myself I would NEVER believe anyone, no not anyone, not even the vicar, the policeman,
The carpet salesman,Nobody

It’s a saga this one one I wish you luck with it.

The injectors are from the old engine, they were running fine before the 'splash' but....

Why did you swap the injectors?

YOU ARE TRYING TO START AN ENGINE WITH A SET OF INJECTORS FROM A WRECKED ENGINE!

If you think the new engine was ok, why put in injectors from an engine that has sucked up water?

Remember, water in the bores, means water in the injectors, or damage to injectors from water being squashed under compression in the combustion chamber.

Surely you must be trying to start this engine in EXACTLY the same trim as it was removed from the damaged car.

Why haven't you mentioned that the injectors where changed?

They were changed because my son is on a tight budget and the vendor wanted extra for the injectors (this is news to me too!). He thought they would be ok since the old engine received damage to its bottom end.

I've given him the money to go and get them, but we're now in lockdown so expect a pause before the next update.
