Does it smoke? If no then you are not getting enough fuel. Check filters and the one in the fuel tap.

Try a SMALL amount of ether/starting fluid. If she starts with that then stops - fuel problem.

In the air intake. But use only a little. I noticed above you were looking for an air cleaner. Is yours missing? Or just pluged? Dandy Dave!

Tried a drop of easy start she seemed to fire up for well a very short time so i guess its a fuel issue?

Yes, but you will need to get an aircleaner ASAP. Because you have a vacuum governor, it will not control the engine properly without an air cleaner and you could over rev her.

Do you mean aircleaner as in the complete oil bath and wire gauze unit ot just some part of it? The engine would be worn out in about a month if used without any form of air cleaner.

How about making a compression test? If it's not had a air cleaner for 30 years I think it's a marvel it would have even started when you got it... I'd never start anything without an air cleaner since I ran my moped without one some 18 years ago and wore down the cylinder in about two months... That's about how serious this is...

like brian said. if theres no white smoke when you crank it, then its not getting fuel, and if it runs with easy start, then you have compression. I would also get an aircleaner as soon as you can, however it looks though you havent got a bulkhead either that separates where the battery is to the engine. Maybe you could find one thats scrap and raid it for bits?
To get it going again, check the fuel bowl isnt full up of sediment, and check the main fuel filter and fuel tap arent blocked, clean them out, bleed the system fully, and then try it again.

Maybe you have a stuck control rod/rack in the fuel pump, some of the symptons sound like what I had when mine would not start. There is a post on here on how I freed it up. Good luck.

My Power Major had sit for some time but it had been back in use and starting ok when this occurred. You can feel the control rod move by moving the fuel cutoff lever at the pump by hand. Move cutoff lever on and off slowly, if you do not feel the rod moving with it then it is easy to fix.

if i take off an injector pipe, diesel squirts about 1.5 meters with quite a strong flow. Try what gman says with the fuel stop switch on the end of the pump first

i have this problem alot with my major theres fuel coming out of the lines had me stumped take the 8 bolts off side casing on the injector pump and move the governor mine always sticks after a few days of sitting around its should move freely and spring back hope this helps :) you can move the cut off line freely but it wont be moving inside the pump for some reason i found goodluck!

not much can kill a fordson

Be careful with taking cover off of pump, any dirt will do damage to your pump. Are you getting a good supply of fuel at the bleed screw on the pump? If not then problem is between tank and pump, start with filter in tank and work your way forward. If good fuel supply at pump then check control rod/rack as stated above. If you push your fuel supply on and then go to the pump and move the fuel cutoff by hand back and forth(on and off) you will feel the control rod/rack and the governor operating, as you move to off postion you will feel the resistance of the control rod and governor. If you do not feel the movement of the control rod and if it feels the same moving it to on as it does moving it to off then it is stuck. I did a post on "stuck control rod" and how easy it is to free up
without removing pump cover. Good luck.

Yes i am getting well what seems to be a good supply from the bleeding nut on the side of the pump also when i pull the engine stop i can see a bar mobing back and forward in side the pump under the four springs the problem seems to be with number one injector pipe of there is a good flow when turning the engine on the second pipe the flow is less and on number 3 and 4 no deisel coming out at all
