The difference is, when you use the hand primer, it sucks fuel from the tank and it comes out fine... Trouble is, you have the injector pump between the primer and the engine/injectors. The pump is your middle man and from the sounds of things that isn't working for you for some reason. Cranking the engine won't do jack unless you have diesel pumped by the injector pump to the injectors...
I'd really be interested to see what / if any codes are on your system.
