This started last fall, tractor would turn over but not start.I changed all fuel filters bled the fuel system,still would not start.
Local JD dealer sent mechanic out,he check for power going to the fuel shut off solenoid and it was not getting power to it.several hours later he thinks it was maybe a ground wire issue,and it started up and run fine. I put the tractor in the shed
for the winter, next spring went to start it ,same thing it would crank but not start. Funny thing is you let it set for a day or two and it would start.Then when I would be baling hay,it would die as if you turned the key off,that time I waited 5 min and it started up and a way I'd go. So in the last few months JD has replaced the check off valve behind the main fuel filter,a braided fuel line that also goes to the main filter,and the fuel shut off solenoid,still having the no start problem.Now JD dealer is thinking it's the ECU (Engine Control Unit).I have around $1400 into this problem and I'm at a loss on what to do.I was thinking some one else may have had this issue with their tractor.Any help would be greatly appreciated. Just yesterday I went to start it and would not fire,check for power at the fuel solenoid, no power.I did not do any thing to it but walked away,The next day it had power to the solenoid and started right up. Thanks
