CK30 suddenly died-won't start

Verify that you're getting power to the solenoid. No click would suggest that you're not getting power (or the solenoid is bad). If need be one can always jumper power to the solenoid: research before trying it!

I'd also look to verify that you're not sucking in air from some place. (fuel filter, lines- perhaps a line got snagged a bit and now has a crack [one can get air incursion while not getting fuel leaking- air molecules are smaller than fuel molecules]).

I dont think I'm getting power to the solenoid. I put the voltmeter pins on the two little contacts inside the plastic connector off the solenoid and theres nothing. Reversed them and still nothing. And the key is on. I know the relay works because that same relay was taken off the starter side and it worked to activate the starter. I see no frayed wires anywhere. This makes no sense.

Have you tested for power at the relay? Should be easy enough to do. Also, one of the contacts may be power and the other ground, but I'm not sure. Try your DVM black (ground) lead to a known good ground and the red (power) lead to one of the contacts on the solenoid.

I confirmed 12 volts going to relay but still nothing on the connector going to solenoid. I tried every configuration and multiple spots on the frame for a ground. Someone mentioned jumping the solenoid. That sounds like a good next step to confirm if the solenoid works or not. Is there a certain way that has to be done?

I think you're on the right track with it being electrical. It you're not getting any power to the solenoid, I'd suspect a power issue with the relay. Can you confirm power coming FROM the relay? From what I recall, you should have 3 hots on the relay---one to power the relay (small wire), one for the incoming power (heavier wire) and another for outgoing power (heavier wire). It'd be best if you could figure out which wire was your "outgoing" power to the solenoid, and test that for power. You may have to poke it with your meter to test for power.

You've confirmed you have power to the relay. I'd forget about the solenoid until you can confirm you're getting power THROUGH the relay. Make sense?

I neglected to mention that you could also test your relay by pulling it. The individual blades should be numbered on the bottom. If you search online for a typical 12 volt relay wiring, blade 86 should be your power source signal wire (energizes the electromagnet in the relay) and blade 85 should be your ground. If you hook up 85 to a ground source and tap 86 with a 12 volt power source, it should audibly click. No click means the relay is dead. It could also mean you don't have your testing wires hooked up correctly, but i'm presuming you've already verified 12 volt power and a ground.

I'm getting fuel all the way down to the injector pump although I'm surprised that fuel doesn't flow very strong out of the end of the hose even when I'm turning the engine over.

On my Kubotas the solenoid is a fuel shut off solenoid, it doesn't click until key is shut off. Could dirt or something be holding the solenoid in cutting off the fuel?

I can hear and feel the relay click, plus when I swap it with the starter relay, which is identical, it works to run the starter. I thought that would confirm that the relay is good. I'll still try to test it with the volt meter after the sun comes up but I have my doubts. I'm really anxious to know how to put power directly to the solenoid and hear that thing working so I'll know the problem isn't likely beyond that in the IP. Is it as simple as touching a wire from the battery to a contact on the solenoid?

This might be of help:

I've never had a need to test thusly, in which case I cannot state with confidence on how to do this: but, it seems fairly straight forward, in concept.

Can you take a picture of your fuel solenoid connection and post it up? I'm showing a 3 pin connector to the solenoid---one each for start, run, and ground.

This is the connector. There isnt enough room to take a picture of the connection on the solenoid itself.
