correctSo with the stop solenoid out, and the fuel lines off and the engine cranking your getting no fuel out of the injection pump?

With some sort of resistance in series (eg: 6v light bulb), I would use a jumper from B+ to the injectors and give it some pre-heat before spending more time chasing possible fuel issues.UPDATE #1
When key is in "ACC/Pre-heat" position:
- Glow plugs get 0 volts
- Stop solenoid plunger extended
Yes, I had the solenoid physically removed and tried starting, but there was no change. Also, watched the plunger while doing this and it worked correctly.Just to confirm, when the wolfman asked if you had the fuel cutoff solenoid physically removed when you did some tests you replied "correct".
I remember you saying you had removed the solenoid and verified it was working and replaced it. Did you actually try starting the engine or do other checks with the solenoid physically removed from the injector pump?
I assume when Wolfman said "out" he meant physically removed. On my BX2200 there is no way to manually retract the solenoid armature other than removing the solenoid from the injector pump.
My injectors are mechanical. In the video I attached to a previous post, you can see I let the glow plugs "pre-heat" for about 15-20 seconds before starting. During that time they were getting 10-11 volts.With some sort of resistance in series (eg: 6v light bulb), I would use a jumper from B+ to the injectors and give it some pre-heat before spending more time chasing possible fuel issues.
The pump is mechanical, and requires a lot of parts to be removed. I would not try starting the engine in this state unless I knew for sure it was safe.OK, late to the post but curious....real curious as a LOT of work has been done on the engine.
It seems there IS fuel getting to the inj pump ,is it possible that the 'injector pump camshaft' or whatever it's called is NOT rotating ?
Maybe a broken gear or key ? Whatever mechanically controls the pump ??
Probably a pain but if the pump is removed can the pump camshaft be seen to spin when starter spins the engine ?
"Diesel safe starting fluid" ???UPDATE #2
After reading the responses (much appreciated), I decided to try the "no fuel" possibility; even though I can hear the fuel pump run and could see fuel filling the filter bowl.
I disconnected the air cleaner hose and applied diesel safe starting fluid directly into the intake... It started and almost ran for a fraction of a second!
Now, I'm considering that maybe the fuel pump works but is too weak to fully pressurize the line?
(Also, verified I didn't accidentally reverse the fuel filters flow... I did not.)
"Diesel safe starting fluid" ???
There is such a thing?
If there is....it ain't "safe"!
Yeah, I’m not an expert on engines, but, when used properly, can help diagnose a non-starting issue.My understanding is that SOME diesel engines by design used starting fluid of some kind.
NOT Kubota tractors though…
I’m at the point that dealer service may be the most prudent next step. Unless someone here can help me have a “eureka” moment.1. You have fuel reaching the injector pump, and returning back to the tank. CORRECT
2. You are now using a different injector pump which is either your original one rebuilt, or a replacement you got somewhere that you have confidence in. CORRECT
3. The injector pump is not outputting fuel to the injectors. CORRECT
It is common knowledge that using ANY starting fluid in a modern diesel will guaranty an imminent death for that engine
That may be true, but I wouldn’t classify my Kubota engine as “modern” since it’s all mechanical without an ECU. Either Way, it didn’t cause any damage, but thanks for the warning.It is common knowledge that using ANY starting fluid in a modern diesel will guaranty an imminent death for that engine
My L48 is from 2006, but I will not use any starting fluid either.That may be true, but I wouldn’t classify my Kubota engine as “modern” since it’s all mechanical without an ECU. Either Way, it didn’t cause any damage, but thanks for the warning.
