There are sleeves that are pressed into head for the injectors to go into they have antifreeze around the outside of them - check to see if loosing compression around them or into coolant

 is this why my machine won't run maybe. my coolant  is coming out around the injector where the hard line screws on top of the block so I need to check those sleeves, and thengo from there to see why I'm not getting fuel out of the line at injector but I have fuel coming out at my liftpump and through my filters do you think it might be my injector pump maybe thanks for the info about the sleeve's I'll check those out thanks again my second tractor and I've never worked on either one until now so all the info I can get is awsome thank you again

I think you have more than one problem here with tractor quit running and also anti freeze leaking around injection nozzle. Realize, that if you pull the injection nozzle, you need to drain the block first so anti freeze will not fill cylinders if that brass sleeve moves on you. I would make sure pump is turning before I got too carried away with diagnosis. They do twist off, and also timing gears fail on bearing.

Take one line off at injection nozzle and see if any fuel at all is being delivered while you are running it on ether. I don't recommend you run it on ether but seeing as how you have been doing that already, once more should not hurt it any.  If you get no fuel at nozzle, pump is bad, or return is plugged. You can take return right at the pump to see if it will pump.  Those pumps can be hard to get the air out of also when you try running it without proper bleeding before you crank on it. Once that air get inside of plungers it just bounces back and forth. Might take all lines off at nozzles also to get it to pump. Oh also, does it have electric shut off. I don't think it does on that model but never know. Those shutoffs conk out and usually blow fuse but they can have open circuit also so it would not blow fuse.

no electric shut off. I can hear fuel running  into the tank from my lift pump when I hand pump it but nothing comes out of injector lines.I have new filters on so I know that isn't my problem.I will try taking all four lines loose and see what happens thanks alot for the info very much appreciated the knowledge from all that have replied thanks again
