.. well starts and chugs a bit then cuts out.
Is there some priming pump I can muck with?
Thanks for any help

Won't work until you get almost all of the air out of the system, otherwise the air acts as a cushion and the fuel will never pass through the injectors, they are spring loaded. Start bleeding the system from the fuel filter, then the fuel pump and then lastly at the fittings where the steel pipe goes into the injectors, right on the cylinder head. You just have to loosen the fittings a little until they start to leak fuel and then tighten them up and it should start with just a little more cranking then usual. You'll have to be turning the engine over with that starter while you are bleeding it, give it full throttle at first, then once it starts to run faster, back off the throttle so it doesn't over-rev.
Be careful not to touch a wrench to the piece of metal that connects to the glow plugs, it might be powered up.
and don't run it out of fuel next time, that's about the only thing that will mess you up with a diesel engine, otherwise they just keep running and running and running...

Thanks, what I feared. I have to get a mechanic out. Do you happen to know where I can get a manual to locate the filter, compression lines etc -I have been working off a scribd online manual and it is very hard to use

Both ran out of gas and had bad fuel numerous times. Well versed in bleeding the 273. You don't need a mechanic, Trials gave you good advice. I have never had to bleed all the way to the injectors though.

Thanks guys.

If you can take good photos and post them here, I'm sure we can point you to the right parts.

It isn't rocket science to bleed a fuel system. Just start at the tank and follow the fuel line. Break it (loosen a fitting) at each spot on the line that had a fitting to see if any air is trapped. Air bubble will come out when you loosen any fitting, but if only clear fuel runs out with not tiny bubbles, then just tighten that fitting back and move on to the next one. Finally ending up with the fitting where the fuel line attaches to the injector. Once you get to the injector pump, any bleeding will have to be done with the engine cranking, but you don't have to crank the engine to bleed it from the tank to the injector pump.
Note that some tractors will have a primer pump located somewhere between the tank and the fuel filters that you can push by hand to force diesel thru the lines. If you have this, then locate the bleeder screw on top of the fuel filters, loosen and then pump the primer till no air bubbles are coming out then tighten the bleeder.
The fuel injector pump will also have a high point bleeder so do the same thing there. Once that is completed, try cranking it before trying to bleed the injectors. Many times a diesel engine will crank after bleeding the system up thru the fuel pump. It may run rough for a few minutes but will eventually clear the air from the injectors. If it wont start, then start cracking the injector lines one at a time as you turn over the engine with the starter. At some point the engine is going to crank up and run. IF it is running rough, then you can slowly crack open the remaining injector lines. Be very careful at this point and only loosen enough to get a little fuel /air out as this will be very high pressure fuel coming out.

Thanks for all the help. I have a friend who is a tractor mechanic here now and it seems the fuel line itself got pinched and maybe running out of fuel was not the immediate cause. The line is pinched where it runs underneath the floor on the way to the fuel pump. The tractor is at an angle and he thinks it got pinched somehow. He thinks it's a regular 5/16" line and he's gone out to get a replacement line. Whew! I was dreading the thought of trailering the thing 65 miles to the dealership.

You get going again?

Make sure to wear safety glasses and gloves when cracking fittings to bleed fuel. NEVER use and part of your body to see if there is a leak- use cardboard or wood, never your hand.
Injected diesel can cause need for amputation of infected area.
