WON'T START

[fbson395]

My L245DT was at a Idle, it started to sputter and died.I checked the fuel and it was empty or just very low, to dark in tank to see. I added fuel and tried to start it. Won't start! I removed the fuel line from the fuel filter to the injector. No fuel comes out of the filter i assume it is gravity fed. some fuel came out of the line to the injector system. Is the fuel drawn up into the injector system and What should I check.I have little knowledge on diesel's. Need Help on this, so please advise on what steps to take next.

Diesel's don't like to be ran out of gas. You now have air in the lines.

Some tractors have a manual lever on the fuel pump. If you have that loosen the injector line and pump that until diesel starts to pour out.

If you don't have that. Then you will have to do it the hard way and start at the lnjector closest to the fuel tank. Loosen it and turn the engine over and over and over until diesel starts pouring out. This is best if you had a buddy to help.

Once the first one starts to pour out. Tighten it, and proceed to the next one. And then repeat until you are at the last one. With any luck it may start up before you get to the last one. You will notice air bubbles, but make sure its really pouring out. Once the air is out. You will be good to go.

Do NOT use starting fluid to help the engine start up even if the can says its safe to use. This can cause a lot of damage to the rings in the engine. Gasoline and Diesel engines have different compression ratios. You can soak a rag with diesel and put that near the air filter. That some times helps if its being hard to start.

Hope this helps

Also you might have to take the filter off and fill it back up with diesel.

If you run out of fuel, you'll have to bleed that lines...

OK, I will try out what you have suggested. Thanks for the quick response. \Bill

Put in plenty of fuel with everything tight ,turn engine over few times, loosen bleed screw [some are on filters ] ,let fuel flow until it stops spitting ,tighten bleed screws ,start motor if it fells to start repeat above procedure. Holt 50

One thing to remember is that on "key off" tractors (ie turn key off to stop engine from running) then when key is off fuel will not flow out of tank.

Don't tell that to my Kubota. If you take the fuel line off the filter outlet and turn on the fuel valve, she will empty the tank right where she sits, key off or on.

The fuel shuoff solenoid controlled by the key is on the inlet to the injector pump. Unless that solenoid is positioned to allow fuel flow, the injector pump stays dry as a bone.

Hello to all, today the wind stopped and so my son and I worked on the tractor. Did as instructed and she started up fairly quick. I would like to thank everyone for their input.Also a Merry Xmas to all. :thumbsup:

Glad you got it running. Merry Christmas

I missed that the first time around... they also don't run worth a darn on *GAS*... on fuel, well, that's another story!!!

Incorrect,

My L3130 will let fuel run out the fuel line until tank is dry. Some of the smaller Kubota tractors do have an electric fuel pumps though. All the Key Stop tractors do is energize a solenoid for around 5 seconds to pull the fuel lever on the injection pump to off long enough to stop the engine and then release it.

The solenoid operated fuel shut- offs that I've encountered were normally closed, and opened when voltage was applied. Sometimes the linkage adjustment can be tricky. If not set properly, they will draw an excess amount of current and can discharge the battery of some of these lower amperage charging systems.

Although this can be the case solenoid operated stop levers are in the minority, the most common shutoff is a small plunger that is screwed into the inj pump that when powered up via the key and is spring loaded to push the plunger out when power is removed, shutting of the fuel supply. Most key off shutdown tractors will not bleed up properly with the key off as you cannot push fuel into the inj pump to bleed.

Just wanted to throw in that I think most of the newer-ish kubotas have bleeder screws. If you run it out of fuel just back the bleeder screw out, start it up, and screw it back in. I've done it a couple times on my L3710
