Diesel CS engine won't start

[HappyCamper]

Hi, my engine overheated after the coolant hoses burst. It seems that the system was pressurised. Not sure why yet. It did start up again but took a lot of turning over and pumping the throttle. It won't start at all now, so I slackened the injector pipe, but hardly any diesel came out when cranking. I took the pipe off from the pump and just a small squirt of fuel comes out. Is this normal, I expected a high pressure squirt, but I don't really know much about diesel engines. I did take a short video but can't upload it until I open a photobucket account.

Did you press the accelerator right down while you were cranking and observing? Obviously not much fuel will be pumped if you don't.

Ah! No, I just turned the key. Would that increase the pressure. The spurt of fuel that came out didn't seem to have much pressure behind it, I was expecting it to really shoot out, but I haven't really worked on diesels before, so wasn't sure what to expect. 
I'll give it a try again tomorrow.

The amount of fuel that comes out depends on how much you press the accelerator . Even then don't expect a flood of fuel. It's only a small engine!

You will get a few drops of fuel at each injector pipe every two revs of the engine.
