This is zzy, I don't know much about computers or tractors but this is my situation. I bought a new 1533 massey in 2006. The only problem I've had is cranking. It will crank and run for long periods of time without any problems but some days without any warning it wii not crank or try to crank. I found if I let it sit for a long period of time it would ccank up like nothing was ever wrong. But this last time after a 3hr bush hog job, I couldn't get it off the trailer. I followed the help I found here and I get fuel to the injector pump through the big nut on the supply line. No air seems to be in the line. I tighten the big nut back down and loosen the smaller nut on the injector getting a good pulse of fuel. I tighten back down. I remove all three injector line nuts and run the fuel pump with no sign of fuel. I crank engine over with no sign of fuel. I did not crank for a long period of time, I didn't think it was necessary. The dealership where I bought it has closed down, no help there. I would like to fix it myself but I need advise.

I followed your instructions with the exception of I only loosened one injector nut and was not able to get any fuel through it. I am excited and hopeful that if I loosen all three that it will be the cure. Thanks so much for the tip

I am still unable to get fuel through the injector pump

Got ya! It almost sounds like you have an air leak. Maybe the filter housing o-ring if you changed the filter just before the problems.

New to your site. Just experienced the same issue with my 2005 1533. Replaced fuel filter, started and ran tractor for an hour and parked it in the barn for the night. I went out yesterday and the tractor would not start. Today I verified fuel to the filter and cracked the bleeder screw to remove any air and it still would not start. Plenty of fuel from the pump to the bleeder screw.I cracked the injector lines and i was not able to move any fuel to the injectors. Any ideas folks?

I had same problem, tried everything as you all. then one day i took the whole filter assembly apart and used a blow gun on all the lines and holes on assembly and bunch of crap came out of assembly steel lines. Hope this helps. oh and the bowl filled right up fast when i turned on the lever when before
it would just trickle till full.

There is a second bleeder screw on the injection pump that you will need to bleed as the remaining air likely migrated to this area over night. Bleed there and try to crank. If it still doesn't crank you will need to bleed the injector lines. This can only be accomplished by turning over the engine to activate the pump. Good luck!
