This 2005 100hp Ag tractor with 3300 hrs is causing me no end of grief at the moment.
About a month ago we gave it a routine service.. engine oil and filter, fuel filters, changed the coolant.
Nothing unusual... later, we worked it for about 5 hours, where it performed flawlessly.
A couple of days later, I needed to have the rear tyres replaced, and rather than pay to have the tyre shop travel 70 miles, I loaded the tractor up and took it to town.
Got to town, threw the chains off and hit the starter.... engine started normally but stopped after about two seconds.. as though the key had been turned off.
Checked fuses and for loose wires but found nothing, engine starts fine, just won't run.
JD dealer is right across the street.. they send a mech. over who finds nothing obvious, but when he holds the key on, after the engine stops, it appears to load up, almost stalling the starter.
Give it a break for a few seconds and it will fire up again, but only for another few seconds.
Took it over the street to their shop and skull dragged it off the truck, where it has been ever since.
They have swapped out the ecu, checked timing, tested injection pump, replaced key switch, checked wiring, checked turbo and air cleaner....still won't run.
When the all the fuel lines are cracked open, the engine doesn't start, naturally, but it does spin on the starter much easier.
I asked this morning if they had tried starting it without the muffler attached and they said they hadn't, but it "appeared" to be OK.
The more I've thought about it throughout the day the more I think it could be the cause of the problem.
Keen to hear if anyone else has struck the same problem before... certainly has my dealer dumfounded and JD Aust. don't seem to be any better.
