Well its been a long road with this tractor, through many glow plugs, a rebuilt fuel injector pump, rebuilt injectors, fixed crack in head and reground valves, motor taken out and rebuilt and new clutch installed. Just starting to see the light at the end of the tunnel. After setting the lash and bleeding the fuel lines I turned it over and started it up for about. 10 seconds just to be cautious. Seeing oil being pumped up to the valves was a good site. But now, I started it up and it runs for about 30 seconds and peters out. It sounds good when it revs up and idles for about the same time 20 to 30 seconds and dies. I did not bleed the hydraulics yet but that should not make a difference I think. I re bled the lines again and verified i do have fuel at the injectors. I did take the line off before the injector pump to check flow and i think it looks ok it comes out about 3/4 full from the fuel line. Any thoughts of things l could try
