5J D2 fuel starvation

[quote="CatsRgr8"]
But one thing I noticed. When I open the bleeders on each pump, I get a surge of fuel for half a second, then just a slight trickle. IS THAT NORMAL?

Good observation. I'm not too sure but that sounds like air in the injection system.

white smoke means lack of compression not lack of fuel so maybe compression test the motor
you will need a compression tester for a diesel motor as they have a lot higher compression than a petrol motor I would expect nothing less than 400 psi
maybe just try squirting some oil down the bores and give it a go if it hasnt be running for a long time the rings might be stuck in the piston and might come loose if you can get it to run for a few minutes
Or may just need a valve grind after sitting for a long time

I'd have thought that with a serviceable fuel transfer pump, you should get a reasonable flow out of the injection pump bleeders, although I have seen it written that the fuel pressure is normally pretty low at cranking speed, but still there should be a flow, not a dribble. One way you can check on the transfer pump is to fit a cap over the fuel tank lid, and put no more than a couple of psi air pressure in there (cut the valve out of an old inner tube, or do what I did and pick up a 4" rubber cap from Home Depot, drill a hole in it, and fit a tubeless air valve to it, and then fit the whole thing on the tank with a clamp. Put some pressure on it and then open the bleeder. If the flow is strong, then you might have a fuel transfer pump issue at cranking speed. Check the fuel inlet adaptor on the bottom of the fuel transfer pump - it has a spring and stop in there that relieves pressure. If the spring is weak or broken, or the stop is not sealing well, that might be your problem at cranking speed (but it's good enough for running speed). I checked the service manual and didn't find a spec for the injection lifter travel unfortunately.
Theres a fellow on here, Bill Walter, that rebuilds injectors and I think pumps (or at least can check them out for you). Contact Bill and see what he thinks.

The comment about the white smoke being poor compression and not fuel surprised me. I thought white mist/smoke/vapor was a sign the engine was getting at least some fuel. I'll try everything suggested. I know the rack is moving and that the pumps are timed to the rack, but I don't know about pump cam lobe wear. When I had the engine running, the fuel pressure was at the top of the green, nearly pegged.

When you see white smoke out of the exhaust during starting, it usually means there is at least some fuel being injected, but not burning. Have seen one or two that had a little smoke but wouldn't run because the throttle was set too low, actually was at the shutoff position still

When you pull the throttle to wide open, you should get a thick cloud of mosquito choking white smoke with puffs of black when a cylinder hits.

When the tractor was running, what did the exhaust look like?
