deutz motor wont start?

[gregdoerfler]

i have a skid steer w/ a 3 cyl deutz diesel motor in it and went to start it after setting all winter and it wont fire, tried starting fluid and wd 40 does not even want to fire, got any sugestions? it is getting fuel at the injectors also.

When you say 'getting fuel to the injectors' do you mean, there is fuel present when you loosen the line? Or do you mean when your cranking its spurting out everywhere?



I ran across an old 3208 that had fuel at the injectors but it would kinda dribble out when the engine was cranked. I had the owner put the throttle to full fuel, and then cranked, and it started spurting out like its supposed to, then the engine started to run, and ran smooth as soon as I got all the injector lines tightened up.



Sometimes the rack, or the linkage in the pump that pulls the pump to full fuel, gets sticky, and won't pull to full fuel. A diesel will not start unless the rack is at full fuel.



Another question is, how fast is the engine cranking over? I have worked on several diesels, that were very picky, and needed every RPM of cranking speed for it to start. Put a fresh battery in it, or the charger on it before trying to start it again.



Good luck

It didn't even try to start when you put either to it?? Was it running fine last fall?

[gregdoerfler]

yes it was running finr last fall, nope nothing with either.

it isnt turning over real fast but tried to jump it and it doesnt help it,there may not be as much fuel squirting out as should be,the throttle was at idle never tried to see how much came out on full throttle but i did try starting it on full.

 

[DavidBurt]

Well if it has good compression and you are getting a good mist of fuel it should fire. I am suprised you don't get anything with the either. Try holding the throttle wide open and put the either to it while cranking it. That is the method we use with stubborn John Deere tractors in the winter. As soon as it fires back off the throttle. It could be a timing thing but I really doubt it as it ran fine when you put it up in the fall.

Good Luck

I completely forgot this question, does it have glow plugs?

Is it an air cooled engine? My dad had a 3 cylinder air cooled Deutz in a Morbark tree shear. One of the tricks they'd use to get it going in the winter (no block heater/coolant exchange possible) was to pull the air filter, and get some newspaper, light it on fire, put it in the intake, and crank it up. Sounds scary, but it worked great, and the thing would fire right off. This isn't necessarily the approach to take, but it is an unusual engine, and sometimes takes some unusual things to get it going.

If the Deutz is not making white smoke out the exhaust while cranking at full throttle it is not getting fuel. I have used a heat gun or blow dryer at the intake to help start a non-cummins diesel.

Sounds like someone borrowed your skid-steer and did not tell you.

My guess is fuel lines leaking.

Is it knocking real loud when you juice it with with gas?

Starting Fluid use

I have seen where an engine would not start and through messing with it and starting fluid the cyl walls got washed clean and hence no compression!



What happens is the problem changed and until we recogtnized the issue we were in a quandry also.



we solved it by putting motor oil in the intake to recoat the cyl walls.



Like others have said the engine must spin over good and fast. The rule is at least 200 RPM cranking speed.



That burning newpaper in the intake sounds like wehn we used to start the old Buda engine!! we used a torch soaked in diesel. .

Didn't you guys ever hear of a propane torch?

 

[gregdoerfler]

it is an air cooled engine, it does have somekind of glow plugs i thought it a a grid heater not real sure. no im sure nobody used it without me knowing it was packed away in our shed, you would not belive how many things we had jambed in there lol. it is blowing black smoke out the exhaust, i think it does not have enough compression. i took out the injectors and filled the cyl's with oil, i will let that sit for a few days. thanks for all the sugestions!

 

[PToombs]

If it is blowing black smoke it has fuel. I'd check for a mouse nest in the air cleaner some place, plugging things up.

 

[MMiller]

I'd check the glow plug system. If its a precup(precombustion chamber) engine, it won't likely start without a couple of glow plugs working properly.

Just like my ford, no glow plugs=no start.

[gregdoerfler]

it has a button that it says to push if starting in cold weather so i dont think it has glow plugs that fire it. i took the intake off completly. anybody know what the compression should be? i am going to make an adapter to go in place of the injector to check the compresion.

 

[cojhl2]

oh mannn,, I think you are skirting around the problem here,, making it more complicated than it is. Whyya taking off the manifold? Didja push the button? Can you find a glow plug? If so is there voltage at the plug? Disconnect the wire to the plug and check for continuity thru the glow plug. Is the engine spinning over good and healthy? Is it still cold there, If so point a salamander at the engine for a spell.



The black smoke would indicate it is getting fuel and fireing it. (Oh now I remember the mouse,, thats why the manifold removal)



All these engines need is 1)Compression, 2)Fuel and 3) 1&3 Timed correctly.



BTW Snapon may have an adapter to check compression. Saves building one.

 

[gregdoerfler]

no it is not cold here, ive started it much colder and did not push the button for the glow plugs, btw i did try the button also.

 

[cojhl2]

Hmm,, bin thinking about what you said re black smoke. Are you sure? I dont think I have ever seen black somoke during start of any diesel. Usually white which is really fuel vapor.



If you do see black then it should be accompanied by the sound of a firing cylinder(s). If thats the case then sustained engine rotation should occur,



The fact is I dunno what is wrong, but am very interested in what you find out. Please keep this thread alive. .
