New Fuel Injector Pump leaking?

That's just bad business on the part of the dealer, if that's what happened. I'd be thinking of a new dealer after this.
The bad IP problem has been on the DK series, not the CK, so this isn't a typical Kioti IP issue.

CM, I sometimes try to just straight start my CK when I think it's at op temp, but isn't, at which point I get your same symptoms until I glow plug it. Too cool of a temp might be your issue, unless you've already proven that's not the issue.

TJP89,

I've been theorizing so far, since we don't have further input from the OP yet. You're right the IP issues have been largely DK and not CK series tractors, BUT the IP's are likely not that different between the two series, though I don't know that to be a fact.

Thinking things through on my rig, I remember that recently I've had some issues with the range control and it's microswitch telling me one thing on the dash and another on the actual shift lever. When this is out of sync I sometimes have to place the shifter in say high range to get the tractor to be fooled into thinking it's actually in neutral. When this happens I will go to crank the engine and if it thinks it's in gear it will start to crank and immediately and abruptly shut off the starter from cranking. Then I 'fool' it to think it's in neutral and it will crank and start.
This error could be tied into the fast crank when warm dilemma, but I'm not certain of that either.

BTW, when the fast crank, (without glow plugs being used) occurs, as soon as I return the key to off, then back to crank, it almost always starts, so I'm fairly certain it is warm enough to not have to do the fast crank/no start routine unless something is wrong in the circuit; which gets reset when I go to key off, then back to key crank the second attempt to start.

I'm certainly in agreement that if the dealer swapped out the IP without it being the cause, (and I'm NOT saying that is what happened), just speculating on their, "ordered the wrong pump" routine, then that would be cause to leave them behind, after dealing with them about it.

And some of what I've been describing with my machine crosses over to the OP's, depending on what actually happened with his symptoms/diagnosis.

So, OP, where are you? We need your help in getting you up to speed!:thumbsup:

What's done is done, I guess. As long as the dealer actually replaced the IP (even if it was good) I don't think Fields has recourse unless Canada has such laws. But If I were him, I'd ask for the old IP to be returned to him. Maybe it's still good and certainly it is repairable and has some good parts that could be used in another IP.

For TJP, both CKs and DKs have had this broken IP gear problem.

News to me.
From what I have been reading here over the years the 2005-2008 CK models were every bit as prone to the IP gear failure as the DK.

CM: You may be onto something here. If the SS plunger didn't retract when the key was turned to on, the mechanic could have been fooled into falsely thinking the IP rack was jammed because the SS spring still held it firmly in the full aft position. You may recall that several other owners on TBN physically removed the SS for this test to ensure it wasn't interfering with the IP rack (and also to ops check the SS by applying 12v directly).

Ritcheyvs,

You stated better than I did what I'm getting at. That's exactly what i'm thinking, especially because of their taking a week and saying they ordered the wrong IP. Now, again to give them the benefit of the doubt, because I do NOT know exactly what happened, but it would be a logical explanation, and the fitting leaking on the pump steers me toward the POSSIBLE lack of skill set of the dealer mechanic(s) in diagnosis and followup repair. Experience in diagnosis of faulty IPs is, I suspect somewhat of a highly trained tech, not a mid-level replace parts after diagnosis guy, so again I wonder what level tech was sent to do the diagnosis. The point we're making about the Stop Solenoid retracting or not and functioning or not as designed, could, IMO, be missed when troubleshooting a no start condition. And I thing at this point a fair amount of techs/dealers may possibly jump to the conclusion that some no start situations point to the IP when further specific rule out tests need to be performed before the IP is chosen as the culprit.

I have only seen DK commonly, I know the CK has had problems too, but I thought they weren't as common as the DK. I believe most of the DK series have a 4 cylinder engine, so wouldn't the attendant fuel systems be different? Correct me if I'm wrong, but almost all the IP pump issues I've read were on the DK.

Also, the first thing I did when I heard about the CK, was to come to TBN and search CK35 problems. The only thing I found was the key switch issue, and the DK IP issue. If I had seen a massive CK IP problem, I would have been MUCH more hesitant about Kioti. In my time reading here, I have not found (IIRC) any threads in which a CK injector pump went just like the DK.

Edit: After reading ritcheyvs link, it appears I am wrong, as CKs appear to actually be in the majority. Guess I have more archive reading to do. Luckily my CK is a 2013.

No, the DK-35 is a 3 cylinder, the DK-40 4 cylinder. The IPs are prone to failure, period. The rack teeth failure is most predominant in all cases, regardless of the series of tractor. Have you read the database link that Ritcheyvs posted earlier?

Noticed, you just added to your post above and are now up to date with the actual data. Noteworthy is the fact that searching some things on TBN have at times proved somewhat fruitless, which may be why you didn't find what you were looking for on the CK series rash of failures over a number of years of manufacture. Also noteworthy is the fact that Kioti does bring about fixes to certain issues like failed pumps. They may take some time to effect the changes, but they do seem to want to have satisfied customers overall. JMHO.

Yup, I have learned something new now:thumbsup: I do agree that the TBN search tool could be better, although I believe it has been improved.

Enough of my hijack though, hope the OP gets things straightened out.
