Hey guys and gals, I have been asked to help get a tractor running again. It is a 2007 JD 6430. The problem started with what is believed to be bad fuel. It had a steady miss and was a bit harder to start. We drained all the fuel and refilled with good fuel, and changed the filters. It started, but had the miss. It progressively got harder and harder to start. Finally it got to where it was backed into a shed to hook up the baler and it quit. Since that time it has not even fired on one cylinder. Another guy started on it and at this time it has had a new transfer pump (think lift pump) and all new fuel lines (the old ones leaked slightly). The closest John Deere dealer is about 100 miles away and now they seem to think it is a solenoid/fuel control on the high pressure pump (we have fuel to the injector (high pressure) pump, but nothing coming out). The only code we get consistantly is for low rail pressure. The solenoid/fuel control is $500+ at one dealer and $600+ at another. I am not going to throw parts at it so does anyone have any ideas?
