Hi Everyone
I have a 1980 JD 650 that was running well earlier in the day until i parked it. When trying to start, it will turn over and spit and spudder some but will not fire up. It has fresh diesel and a new fuel filter. I have bled the system according to the manual and still only get greyish white smoke while turning over. I am pretty sure I'm not getting enough fuel pressure coming from the injection pump. I have good fuel coming from the fuel filter to the pump inlet but when I removed a line from the injector and turned the tractor over, it does spit some fuel but has hardly any pressure behind it. According to the manual the pump should be making about 4500 psi pressure and i need like 2200 psi to push through the injection nozzle. I am not even getting enough pressure to the nozzle to put a hole in a piece of paper. Please help if anyone has other ideas or has run into this issue....
