Turn the fuel cut-off tap off, remove the sediment bowl, remove the rubber sealing ring above the bowl and turn it over and refit. Refit the bowl and tighten the styrup, turn on the fuel tap, let the fuel run into the sediment bowl by slackening off the styrup to allow the fuel to run until it starts to overfill and run over and tighten the styrup up again. I've said this because sometimes when the sediment bowl has been removed, when you re-install it to the lift pump if there is not enough fuel in it it will not create the nesecary pressure to feed the injector pump properly with the correct volume of fuel, it has the effect of fuel starvation. This may not be your problem but the first place to start your investigation.

Agree Powerrabbit,

The tractor is starving fuel or has still some air in the pump. Even if there is some grey exhaust when cranking the mixture may be too lean for firing up. A tiny, yes tiny, sniff easy start may do the tirck and make the engine run. If its just air problem the problem may cure itself. If there is an air leak, the tractor will stop afrer running for a while.

What sort of air temperatures are you having where you are? Diesels start much better with warm air. Since it is warming in the Northern Hemisphere, I would imaging it is cooling in the South.

30 seconds, timed? or seems like? 30 seconds is about the limit that I will crank one before giving the starter a rest for fear of overheating it and throwing solder. Lucas starter motors are finicky to start with, no sense in pushing them to the breaking point.

Do you use the cold start device on the injector pump

I would consider replacing the lift pump
there is a fiar chance the actuator is well worn by now
also it could be muck in the poppet valves
how is the diaphragm?
at the same time I would replace the filters as well
anything slowing up the fuel to the injector pump will not be helping

seeing as it use to start fine but is now playing up after you have played around with fuel system, i suspect air is leaking into the system, the fuel pump is probably remaining primed but needs cranking to get the system preasure back up to where it should be, you could possibly eliminate this by pumping the lift pump up before starting,
