L2250 fuel problem

[MSMike]

Hey guys first post long time reader.

Acquired an older model L2250. Story was guy that owned it ran it out of fuel it sat up outside for last 3 years at a shop. Shop told him it needed an injector pump and injectors because nothing was coming out of it and he didn’t want to fork out the 1800$ since the tractor is so old so I was able to get ahold of it.

I put new filter and bowel, new lines on everything fuel related due to them being full of rust. Pulled hard lines 2 /3 were clogged up but now open. Put new lift pump on side of injector pump, pulled injector pump and fuel rail was seized up ( cleaned and moved freely now). Wasn’t gettin anything out of 2/3 injectors But after some outside cleaning and good diesel in them with diesel clean I have all 3 spraying about 3 inches up when I try to start. Went through bleeding procedures got bubbles and fuel at engine and tightened up so don’t believe any air lock within fuel system but I can’t get it to fire. Tried using hair dryer into air intake to warm everything up and glow plugs seem to be operating as they should. Double checked fuel stop solenoid and it plunged correctly.

Couple questions are
1) how high should the fuel be spraying out of the injectors when I try to start ?
2) is it possible the fuel cutoff rod is malfunctioning?

Any suggestions would be greatly appreciated. Thanks in advance Mike

If you are getting good fuel at the injectors, the injectors might be full of rust. Pull them and have "the guy" do a pop test.

Pull the injection lines and injectors, install a injector line to the side off the engine, add an injector to the line, do not tighten till you bleed air out one you do that tighten line to injector and check with cardboard if injector is putting out a mist pattern.

If not bad injectors.
If they are, you have other issues, like low compression.

Pulled injectors no need to pop test them. The tips are completely rusted up and gummed up. I think at this point a set of new ones would be better than trying to clean these. Thanks for the suggestions

Mike, if you're needing fuel related components like injectors or IP I would highly recommend these folks. https://oregonfuelinjection.com/

You can call them on the phone and get competent, straight answers. The ship as they say, usually very quick to deliver, and very reasonable prices.

A couple of years ago I needed an IP for an L305. Kubota wanted $1100 for the pump, and I had to prepay and wait for some time to get it. I finally contacted Oregon Fuel Injection and received a brand new pump at my house in 3 days for $426.

Most after market injectors are a test of your patience. You get your machine all set up, new injectors ..... and it still runs terrible. You have to remove them and start where you should have in the beginning.

Injectors from OFI "work" when you receive them!! Good luck in getting the tractor going. And welcome to the forum.
