Trying to start a 4010 diesel. The tractor belonged to my deceased, elderly neighbor (thought quite a lot of him - one of the finest men I knew), and I'm trying to get it running for his widow and son. Not a JD man by any means, but I know I should have fuel at the inj. pump when I crack the bleed screw. I've put 25 gal of fuel in the tank, changed the filter, bled it at the filter, and took the line off the top of the inj. pump. It's getting fuel there. The elbow going into the inj. pump is not obstructed (took it off and looked). Thought yesterday it might be the lift pump, but when you pump it by hand, it shoots a good stream of fuel. Also cracked the line at the injectors on #1 & 5, and when you crank the engine, a little fuel will dribble out & slowly run down the side of the engine. Batteries are up and crank strong. Is the metering valve hung up? I disconnected the shut-off cable from the arm and worked it by hand real fast several times, but made no difference. The tractor hasn't been ran in months. Not sure where to go. Hate to tell the family it may need injection pump work, but may have to. Could the lift pump still be suspect? I also drained some fuel out yesterday and it was trashy. Possible damage to lift pump? Have I missed anything?
