With only 200 original hrs. I wouldn't expect that to be off.
So today I called JD service dept. again, this time got the manager to look up "detech"(am not sure if that's right or is it "detach".) Since it's a Delphi pump he is telling me that if it's putting fuel back thru the return line under pressure then it's a blown "membrane" inside the injector pump. This also agrees with the rebuild guy whom I also talked too today, he said it would be a blown diaphragm in the pump. So tonight the plan is to get the pump off and get it to him tomorrow.
Ours was a late model as well. Pretty sure it was a Delphi pump,now that you say it. I remember the service manager talking about a diaphragm in the pump that goes bad. I think age is as much (or more)of a factor than hours.I think you're on the right track.
Timing shouldn't be an issue with those hours except for the fact that Mother Deere set them slightly retarded from the factory for emissions purposes. They'll run and sound better if you advance them about the width of the timing line, IMO.
FWIW, Good luck!
