1910 stalled / won't start

Re: 1910 stalled / won\'t start

I'm not familiar with a 1910.. i've got a 1920...
I'll go with the others.. an air leak on the suction side of the injector pump is going to make starting difficult.

One more way way way right field outside possibility...
Does your injector pump have a fuel shutoff solenoid?.. if your machine turns off when you shut the key of, then yes it does.... Check to see that a wire didn't get pulled off the solenoid.
If while you are bleeding the lines you don't get any fuel, it may be the solenoid stuck closed... but really sounds like an air problem..

good luck,

soundguy - no solenoid
djradz - I think those are the steps I needed. I;m making a couple of assumptions though 1) the high speed tube bleeder screw is a screw (there are a bolt which looks like a fill hole and then the fitting with a screw on top) and I can just loosen the fitting as it'll be a pain to loosen the screw and 2) I'm supposed to close the bleeder on the pump before I crack the injector bleeders - right?
I'm feeling more confident with the help of you guys and the dealer. I discussed the bowl filling up with the the dealer and it seems it was taking much to long 3-5 minutes. Dealer suggested I blow out the line with compressed air. Sure enough, bowl is now filling in about 30 seconds or less. I only attempted a little bleeding (battery was weak) but I think the correct bleeding procedure and blowing out the lines SHOULD do the trick.
Now, bad news, this means I've got quite a bit of junk in my fuel tank (again - assuming) so what do I do to solve that?
Wish me luck guys, every day this thing isn't running is killing me!

AV, I think you've got it!!! The setup is similar to my old 1720, but I'm not sure of the screw vs. the bolt. I'd try what looks easiest. My 1720 used to have a bolt with a hole in the side of it, but yours could be a little different. Anyway, once the fluid flows easily to the bowl, it should also flow easily to the top of the pump. I'd do some serious cleaning of the tank before doing much of anything more. If it took compressed air to get much flow at the bowl, you've got a major problem in the tank or the line to the bowl. Can you see into the tank? Park in a dark location and use a flashlight maybe. My guess is you've got some gelling or rust or other gunk. I think I've read somewhere that diesel will even support some kind of mold or algae growth if enough moisture gets into it. Anyway, that filter bowl should fill up in a matter of seconds! Even if your problem turns out to be something else, your current situation with fuel flow (or lack thereof) is not right. Lastly, yes, before doing any bleeding of the lines or cranking of the engine, close the bleed screw/bolt (whatever) on the top of the pump. As NH states, fluid should have flowed freely by this time.

OK, makes sense, thanks again.
Now, what does cleaning out the tank entail? I'm assuming I need to remove it from the tractor - then what? How about additives / cleaners for diesel?
Hopefully, I'm not jumping ahead and will have it started tonight!

Re: 1910 stalled / won\'t start

If you can remove it, that would be the easiest way to clean it. That way you can add clean fuel, slosh it around, and then dump it. Then do it again and again until it looks clean. I've even hear of putting a few small stones or larger nuts and bolts in to help with any scrubbing action that might be necessary. Obviously, anything you put in must come out. If you can't get the tank off, I really don't have any suggestions other than siphoning off, refilling, and then doing it all again. You should look to see if there's some type of screen or filter in the tank which also might need to be cleaned or even replaced. I'm not sure what a 1910 has. When you're all done, I'd just add good clean fuel. I prefer to purchase it from a gas station that services diesel autos rather than from a fuel supplier, but everyone has there own opinions. Stay away from any place where there fuel is stored above ground or gets very low usage.

Thanks to everyone's help I got the 1910 purring good as new last night. That bleeder screw on the pump really did the trick as soon as I figured out how to use it! I must of just about bled the injectors too because it almost started while I was just bleeding the pump. FYI, it seemed I also had an air lock on the line between the filter and pump. I opened it several times before starting the bleeding process and watched air escape.
hopefully, the tank won't plug again until a rainy day. When it does, I plan to remove and clean it and replace the seals around the banjo fittings.

Re: 1910 stalled / won\'t start

Good to hear. I'd be cautious about using it though until I got the tank clean. If you had to use compressed air to clean out the line, I suspect it may not take too long to plug again. If you can see junk in the tank, I'd take care of it immediately. Anyway, glad you've figured out what was happening.
