I am trying to figure out why a friends 1700 won't start.
The tractor was run out of fuel so i bled the injector pump after reading this post http://www.tractorbynet.com/forums/nh-buying-pricing/84052-injector-pump-oil.html. I loosened the injector lines at the top of the injector pump and saw fuel bubbling around the nut but when I loosened the injector line nuts on the injectors (and tightening the ones on the other end) I could not get any fuel to flow to the injectors. I tried removing the lines and blowing compressed air through and they don't appear to be clogged.
The next confusing thing is that where the injectors thread into the head fuel appears to bubble around the threads when the the engine is cranked.
