Help with fuel system question -BX2200

[rjmatt]

Hello everyone. I'm new to the blog, and the proud new owner of a used Kubota BX2200. I've had the tractor for about 4 months and have had no problems. However, yesterday I was clearing the driveway of snow and the engine started to slow/cough. It never died, but lost power. I shut it down, checked all the fluids, and started it back up just to drive it back to the garage. During that startup, and now as well, I don't hear the fuel pump when I turn the key. How do you recommend I troubleshoot? Could it be as simple as a blown fuse (where?), or does this mean the fuel pump is blown? It's been cold here in CT, but I do put diesel fuel stabilizer in the fuel...would the pump not make noise if the fule is gelled?

Any help would be appreciated..more snow is on the way!

By hearing the Fuel Pump do you mean a defined click or clack noise? If so that may be the fuel solenoid being activated.

Does the tractor run well now?

RJ,

Welcome to the board and to your BX. I had a stick hit the wires to the fuel pump. I had to rewire the pump. I know you were plowing snow which means the entire bottom of the tractor is exposed. If you picked up a stick on the driveway this would have occurred. Take a look at the wires to the pump and see that they are OK.

Other things to consider with a diesel fuel once you get the pump running are: 1. A clogged fuel filter, when was the last time they were changed? 2. Water in the fuel line, do you use a fuel conditioner in the fuel?

Hope you can solve your problem. The folks here will help u until you do.:thumbsup:

Read the following!!!!!!!

If your indirect injection pump is shot your looking a huge chunk of money,

You dont have or need an electric fuel pump on an indirect injection diesel engine and I sincerely doubt the injection pump is bad as they last for many hundreds of hours of operation.

You have a gelling problem with the diesel fuel and its summer blend fuel.

I would heat the tractor up with a salamander/kerosene forced air heater to warm up the tractor before you use it (if you own one) or purchase a small salamander to warm it up(they come in very handy believe me) the purchase will not be a mistake for you.

You could add a splash of kerosene or gasoline to thin the fuel and after a bit of running it will thin the fuel out and reduce the gelling to all most none.


If you have water in the fuel which is most likely you will need to drain the fuel, change the fuel filters, and purchase new diesel fuel after you take the old fuel to a gas station for safe disposal.

Hey guys, thanks so much for the advice..keep it coming! Let me answer a couple of your questions and then I have another of my own.

When I got the tractor in October, I did the general maintenance of replacing the fuel filters, changing the oil, and a new transmission filter. Not to say that the fuel filters aren't clogged (haven't checked yet...see below) but they are not old. And yes, the tractor will start and run, but I don't know for how long since I parked it as soon as I had the issue. Since I'm not hearing the pump I just assumed I shouldn't run it.

I've got the tractor in the garage now, and fired up the kerosene heater as recommended. Once it warms up, I'll get underneath to check the wires (that would be great) and fuel filters as well. I'm hoping that it is a gelling issue as noted, but I have a question about that. Is it normal in a gelling situation to have the fuel pump not pump? In other words, normally I turn the key and hear the bzzzzzz noise of the pump, then turn to the glow plugs, then start the tractor. Right now, I don't hear that noise. Is that because the pump can't 'pump' in a gelling situation?

Again, thanks so much for the help. I'll be laying under it in a couple hours when things warm up!

You do not have an electric fuel pump
as the indirect injection fuel pump does
two jobs; it pulls fuel from the fuel tank
and pumps the overflow unused fuel back
to the tank to aid in warming the fuel and
to keep it flowing as well as not wasting
any fuel.

its the shut down solenoid you may or may
not be hearing. All the Kubotas I evr dealt with
had manual decompression and manual shut down
levers/cables.

You do have a small electric fuel pump and it has likely quit either a bad wire or the pump failed. It is about the same size as your fuel filters and they usually place it between the first and second filters.

Yes your tractor DOES have an electric fuel pump. It also has 2 fuel filters, one next to the fuel pump and the other in the engine compartment. And yes you should hear a clicking sound when you turn on the ignition. If it not running it is either the wires got clipped as I said before or has failed. I have been on TBN since 2002 and I can not recall anyone saying they had to replace the fuel pump on a BX.

You do have an electric fuel pump. The fuses are right next to the battery. The battery is behind the cowl right under the steering wheel. The fuse/fuel pump may or may not be the problem. My BX22 ran ok with a blown fuse, but I wasn't working it at the time, so don't know how the power was. I'd for sure get the pump working before you troubleshoot any further. I believe its the same fuse as the tail lights, so if you have tail lights, I think the fuse is good.

You may find that the pump is fine once it is free of any gelling issue. The clicking noise is a part in the pump that shuttles back and forth to pump the fuel. You may also notice that a pump that is working correctly will change it's clicking with load and pressure... this is normal. These pumps are simple and do not fail very often. As others have said, you will find it between the two filters, under the tractor.
I expect you will find a little gel, gunk or ice in the line. Clean it out and you will be back working.
