Turning the engine 180 degrees and rebleeding was also new to me, it doesn't say in the bleed procedure from Bedford, but I guess it could still be worth a try to hopefully release some potentially trapped air inside the injection pump.
Keeping my fingers crossed that the filter screen is blocked... 
PS! Regarding starting spray I've already tried that, and I know how to apply it and that's it really not healty for diesels, and that one must under no circumstances glow when using it. However, since the engine is worn/has a reduced compression the risk is less. The problem is, that the engine starts on the starting spray, but stops as soon as we stop supplying. Strong evidence for the lack of injected fuel. |
One last thing I have just thought of it to make sure the lever on the lift pump is at the lowest point on the engine camshaft when you use the hand primer.
This is so that you get a full stroke on the diaphragm to deliver the maximum amount of fuel. You can tell what position it is in by the resistance on the hand primer.
