Possible Fuel Pump???

[cnorth]

I have a CK25 that will turn over but will not run. This is a list of the stuff I have checked:
-It has diesel
-I have tried to use ether but it still does not start ( I only did it twice using 3 short bursts of ether on each try)
-I have loosened one of the metal lines from the fuel pump and no fuel squirts out while starting
-When I turn the key to the glow plug warm position, I can hear/feel a clap from the solenoid on the fuel pump.
-I tried taking the solenoid off of the pump and tried to crank again; nothing


My question is two-fold: One, is there anything else you all recommend trying before I concede it is the fuel pump and take it to the dealer? Two, do you all have any recommendations/tricks to try and get Kioti to pay for a defective pump with 190 hrs. on it!?

Thanks in advance for your help. This forum is full of great info; wish I would have found it sooner!

Make sure the fuel filters are not clogged. Bleed the fuel system. See if you have fuel to the injection pump. A good dealer should take care of you if it is a defective pump. Ken Sweet

More than likely it is your injection pump. There are many threads, many complaints, questions that have referenced the same symptoms. If you are mechanically inclined and have a book to show you the removal process - Do it yourself.' It takes about an 2 hours.

Verify first your lift or transfer pump is pumping fuel to the injection pump. If it is there will be fluid pumping out the rubber line when removed from the injection pump. If not purchase and replace with a new one.

Warranty - You will have to talk to your local dealer. We are in Richmond, VA - If you're close come on by and we'll talk or call. I know what I can and cannot do.

Hey, I can assure you that it is not ignition related!....Oh, not funny....

Do a check systematically: Make sure that the fuel supply hasn't been inadvertently shut off.... see that you have fuel coming to the delivery pump, then see that the pump is actually pumping fuel through the final filter to the injection pump. Make sure all of your line fittings are well gasketed and not loose enough to leak. Injection pumps pull fuel in little very stout jerks and will pull air in at a loose fitting and in that case the injection pump will do absolutely nothing. Most of the current injection systems will self bleed but it must have a positive pressure from the delivery pump. Do Not put a finger over an open injection line to see pressure or fuel because it is delivered in very small amounts under tremendous pressure. (You probably already know about this - just cautioning again...)You have a fuel leak.... is my guess. You can find it...

Also; prechambered diesels will very often not start using ethyl either. When you get enough into the induction filter the engine will probably pre-ignite lock - bad!

OK- I tried all the ideas you all posted. Thank you for your time.

As best I can describe, The fuel leaves the tank and goes into a round thing with six phillips head screws on the faceplate on the side of the pump. Is this the other "lift or transfer" pump? Then it leaves and goes up to the big fuel filter. It leaves the fuel filter and goes into the injector pump. All the way to where it goes into the injector pump it will "puke" fuel in spurts when I try to start it. I assume at this point it is the injector pump, but if I did not do something right or need to do something else, let me know and I'll try it.

As for LaVoie, I was talking to a shadetree mechanic that I know who says the timing will have to be set or make sure the timing is set (so that it delivers fuel at the specified time each cylinder needs it)... is this true and what will that involve? Sounds like something that will be very important and I'm not sure I would have the tools to do it. I can follow directions (I am married, after all) but is this something an average handy person can handle?

If you have fuel to the injection pump and not out, sounds like a bad pump. If no one has adjusted the timing, there is no reason to think it would be out of time. Ken Sweet

Man- you guys are fast! So just to be clear, it is a "plug and play" installation. No tuning or adjusting after I take the old one off and put the new one on?

What do you mean by 'pukes'? You should see a nice full gush of fuel from the lift pump line. It may resemble a 'puke' when it is restricted, not pulling a full volume of fuel from the delivery line, or sucking air somewhere between the lift pump and the fuel tank. Unless that injection pump is known to be a piece of junk, you may wish to explore a bit farther. And yes, there is timing involved and unless you set the engine at a reference point before you remove the pump, you have no way to know where it will need to be even with a master spline. The injection pump drives from the cam which is half crank speed so you have half a cycle to be off - 360 degrees...

Timing will NOT have to be reset unless you have power problems.

When you remove the Injection pump from the engine there are shims underneath the pump between it and the engine block. DO NOT lose any. Use the ones they gave you and install the new injection pump. This tractor does not have slots on the injection pump to adjust timing.

NOTE: You will have to remove a couple of things before you can remove the injection pump - 1. Idle adjustment bolt, 2. Stop solenoid and PLASTIC guide (if you don't you'll break it - and it may not want to stop.). Other than that it is plug and play. See attached.

If your mechanic buddy is concerned, you can purchase a Shop Manual and go through the explained steps and time accordingly.
