The good thing about an old diesel is, if it doesnt start , it usually is a fuel problem , cause thats all there is .
However , yep , there's always an however .... , these engines require an enomous amount of pre heating to start, so the glow plugs have to ALL work.
Also , to keep the compression in the right place , the valve adjustment needs to be correct.
To prime the fuel , pump the hand primer many times whilst the top bolt on the filter housing is just cracked loose, pump untill a clear flow of fuel is pushed past the bolt. THen tighten it up. It is important that there is no air in the fuel system.
If you want to , you can pull the glow plugs and put 12v across them and visually see them glow. There is probably a fuse in the circuit somewhere , that you could check, but I dont remember that bit.
I just bought a new slave cyl , being the easiest option for me, I also had the clutch master cyl stainless sleeved , all's good now.
