Make sure that you pump until all the air comes out, it may run clear for a while and the come bubbly again. Start at teh nearest point to the fuel tank where you can bleed and start from there.
I know on some tractors it helps if you loosen the pipes on the injector union at the engine and turn the engine over on the starter and let fuel come out of there, don't undo it tho, just so that fuel dribbles outa there, and when it goes clear, just do it up whilst your still turning the engine over.
Thats another point, when you do the bleed screws up again, amke sure that you're still pumping whilst you do them up, otherwise you get air back in there.
Good luck

Just to add, you don't have to worry about the fuel being clear at the injectors, just let it squirt out for a bit, stop cranking the engine then tighten them and then try and start the engine and it should work

The book way is ok, but you must be patient with the hand pumping, - the fuel flow from the bleed screws must be totally free from bubbles. Then loosen the fuel line nuts at the injectors and start cranking the engine. With half to full throttle you must have healthy squirts of fuel from the fuel lines, and while cranking, tighten one nut after the other, and I think the engine will start at the first tight nut. You won't smell so nice after this, but it works (at least it did for me)

fill with fuel,loosen the fuel line at the injection pump and start pumping the transfer pump by hand til about a pint runs out. This will be enough to get the air out of the filters and lines. Tighten the line back on the inj. pump and unscrew the bleed screw on the inj. pump . Pump the transfer pump a little til fuel flows from the pump housing.Tighten the bleed screw and loosen the injection lines at the injectors and crank the engine over till fuel starts to squirt out. Tighten the lines and it should start. good luck, David

David,
it feels like the little hand pump is barely pumping fuel.. do I have to hold the handle in or is there a trick to that??

you may have to rotate the crank one turn to let the lobe on the camshaft (that drives the pump) move far enough so the pump gets a full stroke. David

Change the Fuel filters and rebleed the injector pump. Bill

The movement of the handle is depending on the position of the camshaft. If the pump diaphragm is alredy moved up, it will only pump small amounts. Turn the engine a little and it might do the difference. Also it feels "funny" when air is still in the system.
