Unlike a petrol engine a diesel cannot have any air in the fuel system as the fuel is injected directly into the cylinders under 30,000psi.
If air gets into the injector pump then you really are in trouble because then you need to bleed the injector pump of air, and then the fuel lines.
So you need to find your fuel leak, either fuel is leaking backwards out of the system or through the injectors into the cylinders.
Does it smoke really bad when you start it after sitting?
Does it fire and run for a second or 2 after it has sat?
Does it spit and sputter for a min after sitting?
Or does it just crank and crank and crank until it finally starts?

Hi Mike,
thank you very much for your help
it does smoke a lot when it starts. It just cranks but wont fire. maybe when the fuel pump & pressure regulator were changed something happened causing a fuel leak. It will start immediately if it has just been running but if left for more than 30 mins it is unwilling and has deteriorated to the point where it wont start at all.... whereas before with the accelerator down it would start. Once it is going it is faultless!! Someone mentioned the plug from the fuel injector wires to the computer might have oil on it too causing a computer malfunction? Will look into theposibility of a fuel leak straight away. thanks again
thank you very much for your help

With it smoking alot when you start it your fuel injectors are probably leaking fuel into the cylinders, it smokes because the extra fuel is being burned off.
It could also be a wiring issue, start there.
We have a truck at work that was hard to start after sitting all night, it was not getting any fuel because of a wiring issue, it would eventually start and smoke really bad.
Fixed wiring issue, no problems since.

Must be nice, diesel has not been below $4.09 or petrol below $3.50 (regular) for over a month here.
