I tipped my F16D over on its left side. No damage was done except to the muffler. I righted it, waited ten minutes, removed the bent muffler, and it started right up. I lowered the front end loader to stabilize the tractor and shut it down again.
No leaks, no apparent damage. Now it will not start. It turns over, catches, then dies. After that, it will not turn over. If I wait a few minutes, the same cycle happens again.
The fuel tank was empty, so I filled the tank, bled the system. Still won't start.
Any suggestions as to what the problem is and/or what to do?
Thanks in advance.
Lou

Sounds to me like a strong possiblity that you may have ingested air into your fuel system when you tipped the tractor over. It may have drawn air up into the injector pump.
Most likely you will have to bleed the fuel injector pump and injectors to purge the air from the lines. This can be done by loosening the fitting nut at each injector just enough to let fuel and air purge from the line while you crank the engine. The pump can be purged by loosening a bleed screw or fitting at the pump until continuous fuel with NO air comes out.
If the engine will catch but die out; you may get lucky and try placing the throttle at full throttle and cranking the engine. If it catches, let it try to run. It will spit, sputter, and protest but if you are lucky enough fuel may be in the lines to keep the engine running to push the air on through the lines and the engine will smooth out and run normal.
Be sure to check the oil level if you haven't already to ensure no oil leaked out.
Good luck and let us know how it goes or if you need more help. ....

It is difficult to get the air back out of the Yanmars. If you ran it dry it is likely to have to bled the system again. I have worked hours on my Deere at times to get all the air back out. The run and sputter is common when it is near empty. ....

Thanks to everyone who replied. I got the tractor started. The blockage was between the fuel filter and the injector pump.
Managed to get the tractor headed uphill, turned around, and back on safe ground. Reattached the brush hogger and came down off the hill, never to return!
Thanks again.
