When you turn the key on, but do not turn over engine do you hear a click on the left side (as your sitting in seat) of the engine? Take side panel off, sit in seat and turn key on. There is a solenoid with a plunger that moves in and clicks when key is turned on. If it doesn't move, reach down and push it forward then start it.
Mine did this, and I cleaned it up and hasn't acted up since.

 

Thank you for answer.

Yes when i sitting on seat and than turn the key the solenoid moved,

When i start first time engine there is ignition and it turn for 2-3 second but when second time there is no ignition but after 3-5 minutes there is ignition again. Maybe there is problem witch timing chain and it jumped clove so the piston don't get fuel when they need?

 

Can you hear the fuel pump running when you turn the key on?

If yes, check the fuel filter.

I had mine die once when I was mowing. It was the fuel pump. I checked all of the electrical connections, pulled and reseated all connectors and fuses. It started and ran, and I haven't had a problem since!

 

I would like to clarify:

When you state you have "ignition" does that mean it is combusting (firing) and attempting to run?

Is the glow plug light, in the instrument cluster, illuminating when you turn the key on and go out after it has been on 5 to 20 seconds (depends on temperature)?

If the glows plugs are heating up and you spray "plak" (I'm guessing that is what we call starting fluid) , it should run at least briefly.

How did you check the injection pump?

 

My starter switch went bad on mine. Wouldn't turn over at all.
I changed and put another switch on mine (push to start), separate from the key switch...
Hope this helps.

About 3 month ago i have the same problem i replace fuse and pump work good, but now i chceck fuel system and the pump and filter is in good condition.

rapidralph:

But when i turn the key the starter work very good.

martincom:

Ignition is were I'm hearing the explosion of the fuel mixture and there is smoke. I'm shure that there is ignition for 1-2 second, after i hearing only starter and tribo engine noise

Glow plug light is working, it shines for about 5-10 second i think it is normal time.

"Plak" is a starter fluid it can start all diesel engine as you said it could run for about briefly on this fluid but on fluid i have ignition only for 1-2 second.

How i check injection pump?
I unscrewed one of the pipes come out of the injection pump and check is there is pressure. There was enough pressure. But when it will by the problem with injection pump it should start with starter fluid.

 

Forsil,

Based on the symptoms you have reported, I'm fearful to agree with you that you may have an internal engine problem and that would be consistent if I'm correctly discerning it has 2100 hours. However, before you dig into that, it may be prudent to check your glow plugs. I'm not real inclined to believe they are your problem, as it initially quit while the tractor was running and hot. However, I don't want to dismiss they could be the source of the starting issues now that the engine is cold.

Yes, you've sure had your problems. I did see your post on your transaxle issues. No, the 455 isn't problematic. I've had one for nearly 10 years with only a few issues such as a leaking water pump and an alternator bearing. I bought another a year ago that had a cracked oil pan around the drain valve due to the internal reinforcement strap spot weld failing. Both of these tractors have 1000 to 1200 hours on them.

I always thought the European version where built to a higher standard, as they came with flashing warning lights, disc brakes, and tail light retainers the North American models did not.

 

I would verify that the fuel control solenoid is pulled tightly closed when you turn the key to run. If it runs on starter fluid you know the compression is ok. I think it is a fuel problem. A partially closed solenoid may be starving the engine of fuel. If that isn't the issue, I would troubleshoot backwards by first checking if you are getting the proper amount of fuel to the injection pump.

 

I agree. The 'ignition' for a few seconds after spraying plak to me indicates that it started but as soon as the plak is gone it can't continue to run because of a lack of fuel. I would first remove the fuel filter and replace the element. Inspect for water contamination and be sure there is adequate fuel flow from the tank to the filter. Then loosen all the injector lines at the injectors and crank the engine to insure there is fuel at that point.

 

I still think it is the fuel control solenoid on the left side of the engine. Mine would move when I turned the key, but I could reach down and push it further. When cleaned and working properly, this should make a loud click when the key is turned on.
If it is gummed up with dirt and old fuel, it may move but not engage fully. Try pushing it all the way forward and then starting it.
If it starts, take the solenoid off and use some electric parts cleaner and blow with compressed air.

 

Also pull the fuel pump from the tank and make sure the sock filter is not plugged up. Algae grows inside diesel tanks, and it's possible the filter is plugged.

 

I'm not too familiar with these yanmar diesels yet, but I'd try disconnecting the fuel shut off solenoid from the injection pump and making sure the shutoff lever stuff is in the run position and try starting the engine. Like I said, not too familiar with these yet but with what diesel knowledge I have I know an injection pump can appear to be getting enough fuel but actually not have enough to pop the injectors atleast at the right time for the engine to run. To me it sounds like fuel supply is low, possibly at the fuel shut off mechanism.

 

If the engine will start on starting fluid, but not without it, it has to be a fuel issue. Only 3 things have to work to get fuel to the engine, the fuel pump, the solenoid, and the injectors. One of those has to be the problem.

 

Thanks a lot for your help,

But today i have a funny situation becouse i call for mecanic and i tell him what is wrong and i sit on tractor and tried to start engine and the engine start at first time! W*F? the day before i do everythink to start engine.

I think you are right that i should check injection pump, probably it is dirty. In fact i cut about 3 acre of lawn, and nothink wrong with engine.

Martincom:

I have tractor with flashing warning lights and disc brakes but i don't see the use of them.

Mayby you are right that 455 isn't problematic, i buy my tractor from privat dealer about 2 years ago and it has 2000 mth soo it is normal that used tractor need repeir. Unfortunetly the new x758 cost in Poland 15700$ with 23% tax it is unprofitable to paid so much for tractor. I paid for my tractor 4200$ and about 600$ for parts and repeirs.

 

I've never seen a 455 equipped with the flashing lights and disc brakes here. The brake on North American models is internal to the transaxle. Likewise, I wouldn't find much use for the flashinglights, except when blowing snow. I have a cab with a warning beacon on top that does that job.

The tail lights falling out is a real common problem on the North American units---not one of Deere's better moments. I ordered the European model tail light retainer brackets for both of mine to remedy that problem.

Yes, 2300 hours is a lot. I wouldn't consider buying a tractor with that many hours unless it was something that was priced right and I had a need to salvage parts from it.

455s with 1000 to 1300 hours are plentiful here. The second one I purchased last spring had 1000 hours on it. When I purchased my first one nearly 10 years ago, it had 650 hours on it. Those are pretty uncommon now, but every once in awhile one pops up.

Wow 23% tax! Is that your only tax? Our sales tax here has just been increased to 7.875% and I'm very vocal about it. Of course, we have both a national (federal) and state income taxes, real estate taxes, to name the major ones.

In Minnesota, our vehicles license plates have the logo "Land of 10,000 Lakes" stamped across the top edge. Those of us that live here refer to it as "Land of 10,000 Taxes".
