I have a JD 50ZTS with a Isuzu 4LE1 engine. It's been running fine but recently started to miss on one or more cylinders. Checked the fuel filters and they were fine. So I thought I would put a set of injectors in as a quick fix (not previously touched) and likely needed. While replacing the injectors the old #1 & 3 were almost completely clean while the #2 & 4 were black with a build up of carbon and soot. I'm not sure why some are clean and some are sooty. So the question is if the individual pump was stuck and not sending fuel to the injector would it cause this? I have not touched the pumps yet. has anyone had a similar problem.
Thanks
