NOT BOTHERED.
Are the heater plugs,staying on for the right amount of time?.

ok,but do they stay on,for the correct amount of time.Ok yours come on,but are they on for long enough.

Hi
Look for an air leak, diesel leek in the fuel filter under the bonnet and from the sedimenter a in the rear wheel arch and the fuel pick up pipe on top of the fuel tank. Clean out the sedimenter and replace the fuel filter in case it has a damaged seal etc.
Also consider replacing the fuel lift pump if you can not find any leaks anywhere else.
Some people look for air leaks by replacing a piece of fuel pipe in the engine bay with clear plastic pipe to see if it is pure fuel being sent to the FIP or if there are any air locks. I am not sure exactly where they put the plastic pipe.

How do i check they stay on. There new plugs in.

Hi
Once the engine is running there is no need to bleed again, as the flow of fuel will flush out any air. However any small hole will let air be sucked in via the Venturi effect.
Are you sure your battery and starter motor are up to the job ? is the engine turning over at different speeds when cold / hot, although based on your original description it sounds like an air / fuel problem or possibly glow plugs ?- is there voltage at each plug and the relay output?

If it starts well when hot that would suggest an issue with the glow plug system somewhere ,check voltage at each plug and how long voltage stays
Were they quality plugs as cheapos can fail quite quick ,if the relay is giving correct voltage for the correct time it may be worth taking plugs back out and checking none have bulged at the ends and test them by putting 12v to them ,they should glow cherry red at the ends
But it could be an air leak ,mine does the same if left over night parked up hill so i always park it down hill

black smoke or blueish/white?
it sounds less like fuel and more like poor compression/knackered injectors
what mileage is it on?
and are you sure your starter isn't being lazy? it should be a fast, strong crank
if it's a bit worn and low on compression, then glows will help. see what happens when you cycle the glows twice.
if you don';t think the glows work. pull the relay and look for the two thick wires and spades. 1 and 2 iirc. joining them together should put juice to the glow plugs.
connect them together for 30 seconds when cold, then carefully shove em back on the relay and see if it starts.
be careful the brown one (1) is from the battery and is live. (actually, follow that back, doesn't it go to some fusable thing on a disco. make sure it's not blown)
got a multimeter?
