(19J) It just won't start...

Stupid question what about glo plugs?

Have you got the rocker cover off ? Does everything move as it should ? Is there plenty of oil ?

Removed 1 and it almost melted the wires I had running to it for the test, so I would say it's getting warm enough to do it's job, given that it was red hot on the bench...

I'm properly stumped...

With the inline pump wired up, I was able to bleed the injector pump with the 8mm bolt on top of the pump, and there was a brave bit of pressure behind it which was a good sign (the inline pump is doing it's job), but even with the inline pump filling the filter and getting diesel to the injector pump, it's still not letting massive amounts out of the injector feeds, but I wasn't expecting loads anyway, just a steady flow which I'm getting.

The timing may not be perfect... but not enough out to stop it running...imho... so...
Have you checked the fuel feed at the injectors themselves - as opposed to the pump outlets?
Spill pipe blocked?
:car:

Not had a rat died up the exhaust or air inlet have you?

As the engine looks reasonable, look to the systems then, all the air inlets, filter etc for blockages, or collapsed pipes .. a diesel only really needs air and diesel at roughly the right amounts and times and it should work!

Slackened the 4 pipes at the injector ends 1 at a time to get it bled the best I could. When I had the pump off getting rebuilt, I blew the injector pipes out with the airline to remove any unwanted debris, so I know they are clear.

I slackened the 13mm nut at the bulkhead end of the leak-off pipes, and during cranking, the diesel was coming trickling out of it which tells me the return system is ok... It's also getting back to the filter, so that pipe itself is clear too.

And that, good sir, is my very reason for taking the 90 in the first place; My thinking was along the lines of "It's an old school diesel. How hard can it be to get going...?"

Chewing those words now though

Also, I'm cranking it with the inlet pipe off the turbo, so I know there's no blockage for the air getting in... Turbo could be in better condition, but as it's spinning under cranking, it should realisitically be allowing "enough" air through, if nothing else..

Emmmm.... it is Diesel in the tank...isn't it??????? :bolt:

does sound like no fuel or not enough that or the camshaft has snapped.

It is indeed. I drained the tank and got rid of all the sediment that had gathered up over the past 25 years, and filled it up again with fresh diesel and a fuel filter, along with all lines blown out...

Well in basics a diesel needs four things

Fuel
Air
Heat
Compression

So you know you are getting heat air and more than likely fuel. So next set would be compression. Have you got a compression tester?

Might have missed it somewhere, but I would slacken off the fuel unions at the injectors and turn it over until fuel is squirting everywhere. You can even tighten them as someone else turns it over.

That's how I was bleeding my 2.5 NA and it worked a treat. It's hard to get the air out of them after major work. I also had crappy glows - having good quality ones (denso, beru etc) makes a world of difference. They should be glowing bright red in a few seconds.

But even without glows I could get mine going (it would take about 30 secs though). Biggest problem I always had though was air getting back into the system hrough the HP injector lines\unions. Changing the set for new ones made a huge difference.

You also need a good battery and the engine must be turning over strongly.

Any luck with this yet?
