Well that leaves you 2 options, low pressure to the injector or the nozzles are blocked.
Now I know next to bugga all about these diesel thingies but my big one lunger Lister diesel had fuel issues and after I sorted the rack on it I tried the pump and it did pump fuel up to the injector but I thought it was not enough so I kept stripping the pump and rack so many times. In the end I connected the injector while it was out of the head and tried it, success. I was amazed at how little amount of fuel that dribbled out of the line would pressurise enough to atomise the fuel so it may be as simple as a blocked nozzle/s

The fuel pressure for injection is 2500-3000 psi...gemerally English stuff is in Atmospheres =15psi.......3000psi is 200 atmospheres.or 200atm...........Big proviso here is that the pump is correctly assembled..............fuel coming from the injector pipes,but no pressure/injection can only be air in the system...........there are no plastic/rubber seals anywhere in the high pressure fuel delivery,all metal to metal.

Other possibility is that timing of the pump is out and is not injecting on the firing stroke. Unlikely I know but...
I have a Case 188 engine and after getting water in the injector pump I rebuilt it with a kit. Exact same problems of not firing and now won't even fire with a sniff.

That would normally be a possibility but we can't even get the injectors to squirt

So I have a plan and will report back on my findings when I know some more

I will guarantee that the problem is air in the pump.......when I have a pump apart I take great care that its properly bled before I install it on an engine.......Saves a lot of drama ...amd cranking.

Is it possible to gravity bleed these overnight, as my Chinese tractor once did after I gave up trying to bleed it the normal way?

Electric pump is the first thing I’d try if it hasn’t gone for a while the lift pump could be sucking minute amounts of air if the diaphragm was a bit dried out
It will also give you constant pressure at the injector pump

Dunno worth a try imho
