CK30 suddenly died-won't start

[MWB1564]

Well, here's the story. Yesterday I was about to lift something with the bucket and the tractor suddenly died just like I turned the key off (no I didn't accidently bump the key). It then started right back up so I didn't think anything about it. A few minutes later it did the same thing and would not start again. It would crank forever but just not fire. The first thing I noticed was I was not hearing that loud click/knock from the fuel shutoff solenoid when I turned the key. I have had to take my ignition switch apart before and clean the contacts so I did that again. They didn't look bad at all so as I suspected that didn't help. Thats about as far as my knowledge goes as far as troubleshooting. I'm pretty sure the fuel solenoid is not opening but I don't know exactly where its located or what to look for next as far as it being an electrical or mechanical problem. Can someone tell me what to check next? Thanks.

It does sound like your fuel solenoid or the wiring powering it. If it lacks a separate fuse you can try following the fuel line from the tank to the fuel pump to locate it.

Havnt looked on mine but isnt the solenoid commonly located on the injector pump?

Check your fuses first to make sure they're all good. A crank no start on tractors is likely a fuel delivery issue (simple things first), so you're on the right track. Like RoadWorthy said, you can typically trace the fuel line to the the fuel filter and beyond to the fuel solenoid and pump.

Thanks, that makes sense. I didn't just suddenly lose compression so the only thing left is fuel. I'll try to locate all the fuses and look at them. I also read on another forum that the fuel solenoid has a 70 amp relay that can go bad? I'll have to figure out how to locate and test that. I'm waiting on a break in the rain hopefully today.

All of your relays are typically on the front of the tractor, right above the battery and radiator. I haven't found any that are located elsewhere...at least not on my tractor. You should be able to find it out by swapping one of the other relays and turning the key to the "on" position. The one that "clicks" is likely your fuel solenoid relay.

I swapped the two 70 amp relays and i have the same result. Is there a particular fuse I should be look for or at? I'm not aware of any in the fuse box under the dash that would associated with fuel delivery. I could be wrong. Or perhaps a in line fuse somewhere?

I think you should try the keep it simple approach first. If it's starving for fuel, you could check to see if it's getting fuel first. Pull the fuel line going to the filter and see if fuel flows freely. If not, you have a line restriction or something in the tank blocking the fuel flow. If it does flow freely, then move on pull the fuel line past the filter to see if it's getting past the filter. If not, you may have a clogged fuel filter. If it does flow freely through the filter, then follow the line to the fuel pump and pull it right before it gets to the pump. If it's making it that far and flows freely, then your issue is possibly the pump or the fuel stop solenoid.

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. There is a steady little stream but I expected it to gush out. Maybe its not supposed to. I've got it into the garage and cleaned up all around the injector pump. Later today I'll take the solenoid off and see if the plunger operates in and out while detached from the pump. If it does then I guess I'll have to assume the pump is bad.

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]).
