YM2210 injectors, fuel pump, problem??

[atsah]

Doesn't look bad from what I have seen.. How about you're grow plugs, have you verified they are in good working condition? You're spray and FP video's look okay to me.. I would check all else before throwing money at injectors that are in fact spraying.. A little different spray but spraying okay none the less..

I only have the one Thermostart and it works fine. I will hook the injectors up when i get home and see how they spay now after cleaning them.
Thanks for the help.

Those who don't know these engines always mention glow plugs. These as you know don't have true glow plugs. Your thermostart has no bearing on your tractor running once it's running. No diesels glow plugs would unless there maybe loose and leaking compression. The thermostart is in the intake and therefore has no bearing on it running if you can get it running. An even weak engine should be able to be gotten running in the summer without it, esp with the help of the compression release.

No, should have been full throttle. You shouldn't have got anything unless maybe your tractor has a kill cable and not shut down with the throttle.

I do get fuel when the throttle is in the stop position, looks like that is out of adjustment to.one more thing to fix :cool2:

That's a good point.
Thanks for your time and help.

So I hooked the injectors up, upsidedown and it looks like one injector is spraying better, the other one is spraying about the same. I will have new injectors tomorrow, so I hope that will help, I'm going to drain the tank change the fuel filter and get some new fuel and hope it will start better, I would like to do a compression test while I have the injectors out but I don't have a gauge to do a diesel, maybe I can rent one, I will just machine an adaptor to hook it up, before I do that I will adjust the valves.

Well I adjusted the valves, man I’m glad I did they were way out of spec.

Hopefully that shut off problem is in the linkage.. if not, the inj. pump is either assembled wrong or it was put on wrong..
When your starting it.. u need to give it some throttle.. at least 1/2..to 3/4..

Yes, most tool loaner places will have a diesel compr. gauge..
the only problem I foresee is, u getting the correct adaptor to hook up the gauge to.. MOST are quick-connects
U can possibly RENT IT from Hoye for a couple of bucks.?? IDK.. but they RENT the inj. removal tool..
I DO KNOW they SELL the adaptor..
YOUR machine "probably" wont exceed 400 psi... but u need a gauge that will accept 500 minimum..
Good luck..

I fixed it with the adjustment on linkage so that is a good thing. You do rebuild this pump right?
Thanks for your time and help!
