Pulling the Only Hairs I have left out!

[Mitch the Roofer]

My 2006 L3130 started then stalled, I changed the fuel filter, primed it, blew the line, charged the battery, checked the air filter, will turn over but not start, not gas either, it's appears to be getting fuel but just won't %^*&^%$ start. Any suggestions will be appreciated, happy to help with a roofing ?

When you primed did you bleed the injectors? I usually don't have to open the lines to the injectors. Does yours have a thumb screw on the side of your injector pump? I open mine up when I first start. Then close when it's running good. I'm running a l2850

I hope you didn't do what I just did and put some gasoline in your diesel tank. It wouldn't hurt to drain the tank and verify the fuel is clean and water free and perhaps freshen it up.

I did the above, still no start, changed the gas too, I know it is something really simple but cannot identify what it is.

Did you check any of the safety switches,, like the seat switch?

Yes I did, not the issue, any idea how to test the compression, I Googled it many times and cannot find out how to perform that task.

I had something similar happen with my 2004 B7500. It ended up being a very small split in the injector return line allowing air into the fuel pump.
Wipe everything clean and look for any trace of fuel on the lines when you try to start it.
B7500 just quit

 

[Mitch the Roofer]

I will try that, the one thing I haven't tried. Kabota dealer says I will most likely need to bring it in, I just know it is a simple fix, just can't figure it out.

Know it's Summer but my tractor needs preheat. Suggest as a last resort you check that glow plugs are working and getting current.

Okay finally got it started, possibly a plugged line, but it is stalling out when I am idling, any thoughts?

 

[mendonsy]

My B7500 has a small lift pump (looks almost like a small fuel filter) that brings fuel up to the main pump. I'm not sure if you have a similar setup but that might be a place to look.
Also ... if it was a plugged line, possibly something got into one (or more) of the injectors. Does it sound normal when it is running???

I worry when anyone states they change the "gas" in their Kubota.
You would be better stated to say you changed or replaced the "Fuel" or "diesel"!
I would look at the stop solenoid first before you get into anything else.

 

[Mitch the Roofer]

I do apologize, I meant the dealer had recommended I start with deeming it bad gas, I have not made the mistake of putting in gas over diesel, just trying to rule out bad gas, willing to try anything, so replaced the fuel that was in with new diesel, but still did not start.

Also, while i can certainly handle easy fixes, I am not familiar with the selenoid.

The selonoid bolts to the side of the injection pump, and has a couple of wires going to it. You can meter the wires and see if your getting voltage. And can unbolt it and make sure the little rod moves when it has power to it. Just be careful that it's straight when you reinstall it. It doesn't take much to bend the rod did that on the first one i ever replaced. Seen other guys do the same thing.

 

[Mitch the Roofer]

Does anyone have a link to a video on how to test,replace, I can find a video on everything but that, thanks for the info.

Your stop solenoid does not bolt on the side it bolts on the front and the rod moves internally in the injection pump.

There are 2 types of solenoids used in Kubota's one is a dual coil type and one is a single coil type.
The first type uses 2 coils, one to pull in the piston and rod and one to hold the piston and rod in.
The temp type is usually triggered by power and used either to let fuel flow or to stop fuel from flowing.

First before disassembling, with the key on and immediately after off take a meter or test light and check for power to the solenoid.
Some Kubota's have timers to cut off fuel for a short period of time, then disengage. Some just power the solenoid the whole time that key is on to let fuel flow.
A bad solenoid on the second type will cut off fuel at anytime when they are bad.

 

[Mitch the Roofer]

Great, I am going to check it now, I assume it is fairly easy to replace?

Mitch, what did you find out with the fuel solenoid?
