Ok, this is a friends tractor, it's a Long 510 3 cylinder diesel. apparently 4 years ago it started running rough and he shut it off. It never would restart after that. It sit for 4 year till now and it was out of fuel.. Dont know if someone siphoned it out or if that was the initial problem. I worked for Ford and worked on the international diesel engines. Well, first thing I did was check compression on the tractor, all were real close and wthin spec's. Then I use a bench tester and found that the cylinder number 3 injector just pushed out fuel, there was no pop=off. The other 2 injectors popped off at about 3,000 psi (500 bar) I then adapted the bench tester to the injection pump and I got over 3800psi. So, we replaced the bad injector with new copper washers and seals. Bled the system as far as we knew was correct but she wont fire. it wont even try to fire. Just blows white smoke out the exhast. We tried spraing a bit of WD-40 in it and it didnt do anything. This has the thermo heater for the intake air. We tried that and could see it was working but this tractor wont even try to pop off. if you remove the injectors and hook them up to the pump and crank the tractor over you get a nice 3 port spray pattern from them, but when you install them, the tractor doesnt even try. I was hoping anyone out there had any idea's I was thinking maybe put soem oil down the cylinders since it sat for long but it had good compression readings. Any help would be great as it is Blueberry season and he needs this tractor running to operate a spray rig. Thanks in advance.
