GU ZD30 Cranking but wont Run

With the ignition on does the check engine light (MIL) and glow plug warning lights in the dash come on?

Does the vehicle have a chip fitted? Make sure the electrical connector at the IP is clean and fastened correctly.

Just a couple of questions, was yours blowing any smoke? did you try to run yours with start ya bastard, as mine ran on it but s*** house, and were there any other symptoms to yours?

I recently had a similar issue (not with a Nissan) and it turned out to be electrical. The engine management system wasn't talking to the electronic injection properly. Any way of checking for codes? See the post from Hodge above about Supercheap.

Yeah my brother said when he opened the return line, he had fuel, that was when priming with the hand pump though. would there be a difference between that and cranking the engine

One other thing, after priming the fuel filter and it goin hard i'd crank the engine (it wouldn't start of course) and then i had to prime the fuel filter again. any ideas on where the fuel could go?

The unused fuel would be returned to the tank I would think.

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.

Does the red security light on top of the dash go out when you are trying to start the vehicle?

I keep looking for this red light at the top R/H corner of the dash and its just not there. Maybe the bulb blew, i'm not sure. I've only owned it a couple of weeks......................wait i went looking and found it under the dash mat

Not sure on the chip, but yeah all lights on the dash come on, its fault code has come up with N.A.T.S so i'll chase that first

Yendor is your man here. He knows these things inside out then. I am glad and I hope it is only NATS stopping your engine from starting, as that is much much cheaper than the injector pump.
