Kubota L6060 Engine failure

I agree with everyone above, and to ruffdog's comment especially. Afaik the injector pump is still mechanical and not connected with any wires to be able to diagnose squat. It would be sad if it was as simple as the fuel solenoid.
Save your parts and paperwork.
Hope this has a happy ending for you.

The computer can't always figure it out, still need a common sense tech to find the bad ground that is giving that computer fits !

It is a HPCR system. Vastly different than what you are envisioning with plenty of wires connected to multiple sensors and the injectors.

Otto von Diesel just rolled over in his grave...."how you people can take a simple machine and complicate the heck out it.."

Do you have the old parts? What was the fault? Dosent work are not an answer after a failure analysis. Was the injectors bad because of a failure of the high pressure pump filling them with debris, thus as an example of a not uncommon failure on common rail engines, what error messages did they get on the ecu?

If the tractor WAS under warranty, would corp Kubota pay for all those parts and labor? I think not. When I was service mngr, the regional service rep would visit and check the replaced parts and review the RO. Who knows what is going on with the OP's situation.:confused2:

I understand....but if it is not running, I question how much info about the injection pump can come from the diagnostic port?

If its a normal system you have stored fault codes in the ecu.

But of course we are talking about a Japanese brand, they might be using totally out dated solutions, often so conservativ and afraid new things that it's ridiculous.

You certainly are right Rick, never thought that type of "stuff" would end up on small engines.
What's your 30,000 ft opinion with all that you've seen in the business?
