A new engine, but not necessarily THAT new engine.
And if it boils down to needing an ECU wiring harness your new engine would have been a waste of even more money.
Yeah- it will be a Real kick in the head- if it is a bad/ intermittent signal from a sensor due to a harness problem.
I could see a bad or malfunctioning crankshaft position sensor among others causing a shut down and then no start condition like this.
But the ECU should keep a record of the loss of signal or signal out of bounds.
Diesels with their high compression Really don't like a mis timed injection event(s). So any faults the ECU sees will trigger a do not not fire the injectors.
Does the Kubota dealer have even basic fuel injection test equipment?
No mention of NOID lights. typical under 100 dollar test equipment for gas or diesel common rail fuel injection .
As a simple test The Noid lights would have told the dealer immediately whether the injectors are receiving firing signals during engine cranking. No flashing Noid, No Injection event, No Fire, No Start.
Also A very easy test to do at the point the dealer says you are at Now, (New pump and ECU) But no start...
Something sure sounds fishy about the troubleshooting to determine root cause so far.
Modern ECU controlled CR was worked on by "FIAT" of all companies sold to Bosch who really advanced it. ( Probably the best purchase Bosch Ever made) Common Rail diesel has been in broad use for almost 20 years.
You would think Kubota would have some well trained crack field agents or at least help line for their dealer techs for a dead tractor like this.
If the (OP) does end up getting charged for parts installed so far, DEMAND ALL of the OLD Parts.
