The rack also cycles when you switch on the key and it makes a fairly distinctive "TOK" sound. Or, it should I would say... If you leave the key in the "ignition" position and don't crank it, the rack will release in a couple minutes and make another, quieter knock.

well still no go. I replaced the SOV but it still won't start. I was able to reduce the bubbles by ensuring the return line was full of fuel, I replaced it and I think it was sucking the air from the line when I stopped cranking. Now that it is full of diesel the bubbles have significantly reduced. I do get black out the exhaust while cranking... Is this a good sign. I have four glow plugs out and it is getting colder here, perhaps that's the problem now. I have plugged in the block heater but maybe its not hot enough to make a difference.

Firstly get hold of some fresh viton or even rubber O rings and redo all the plastic pipes on the pump/filter. - Be sure to remove the prefilter strainer and replace its O ring too. Clean the strainer while its removed.

Also buy a bulb type diesel fuel primer pump - pump it up, you can also subsitute this with an electric fuel pump. This makes sure our pump is getting all the fuel it wants.

I would also try a part gasoline part MMO mix in the pump to free up any globs of grease that build up and cause the pump to stop working. (saw a similar case very recently - the amount of greasy slime was incredibly bad).

Hope your engine has compression, rings can stick hard in their grooves with such fuel being burnt in the combustion chamber.

It lives! I left the block heater plugged in all night, woke up this morning, gave the intake a shot of wd40, followed by a hairdryer. After cranking for about 30 seconds it started right up. There is no longer any evidence of bubbles in the fuel lines.

I think my problem was when i replaced the return fuel line from the fuel filter to the hard connection on the firewall. It was obviously full of air which was being sucked back every time I stopped cranking. I attached a brake bleeder vacuum pump to suck fuel back to the firewall connection which solved the problem.

I hope my experience helps others who run into a similar problem. Thanks for all the help!
