First off DO NOT USE EASY START. It'll clear the build up of deposits from the cylinders and result in it being harder to start in the future due to low compression.

Did the fuel pump whine quieten down? If it didn't then you still have air in the system. Did you fit a good quality fuel filter? Britpart and other poor quality filters are notorious for causing running issues.

Try turning the ignition on and pumping the throttle pedal 5 times in quick succession. This should put the system into 'purge mode'. I fitted a fram filter to my TD5 a couple of weeks back and had to purge the system 9 times before it quietened down.

Did you give the glow plugs a couple of glows to help it ignite the fuel?

the pump is still abit loud yes and the filter is brand new i havent even ran the car with it on yet its like its trying but just won't fire up.

did you fill the new filter with diesel before fitting it? If not it needs further purging.

And ive got fuel upto the injector i unclipped the pipe pulled it of and turned ignition on and fuel pumped out so the fuel is upto the injector

No i did'nt fill filter with fuel i thought it would fill itself

If there is air still in the fuel, the fuel can not reach a high enough pressure.

It will but will but it needs to be purged thoroughly. As a general rule, If the pump is still noisey, it still isn't purged.

so how do i perge it and how do i know when its purged because all i have got is the ignition on for 30 seconds then off for 15 seconds and repeat this 5 times thats in the handbook

1) Turn the ignition on.
2) Wait for the fuel pump to stop whining
3) Pump the throttle pedal 5 times.
4) The fuel pump should restart and run for a couple of mins
5) Repeat this several times over.

Then try and start it.

It took 9 cycles of this to get mine to go quiet a couple of weeks back.

And this is for the Discovery 2 TD5 sorry to be a pain just making sure one things for sure its going on ebay when its runing bloody thing.

and what if my pump is constantly running?

Yes. It should work on all TD5's.

It isn't purged. Wait for the fuel pump to stop and then do it. If it doesn't work then it sounds like you have one of the earliest TD5's. They purge by turning the ignition on. Just turn the ignition on and wait for the pump to stop. When it stops, turn it off and on again.

Is a 1999 mate as i say i have done the on and off thing with ignition like it says in the handbook but no joy

By the sound of it you have the early priming system.

If the pump hasn't stopped after 30 seconds, let it carry on going. It'll run for a couple of mins and then stop. Turn the ignition off and then on again and it'll do it again. Do this several times and then try and start it.

bet you it starts.

my mate has rung me he got it running he said it was chugging on 3 he went a blip down road and its running mint now thanks alot Ratty ebay here i come LOL!

Really?

You have undone the fuel pipe to a TD5 injector?

I don't think so.

You have air IN THE SYSTEM.

Turn IGN key ON. Leave it ON all the time from here on.

hear pump squealing. When it stops deck the throttle five times and the pump will start again.

When the pump starts to quieten down, REPEAT THE PROCESS FOUR OR FIVE TIMES MORE..

Now sit in car. Turn IGN OFF

Turn IGN ON, wait till glowlamp goes out, DECK THE THROTTLE ans run the starter till it fires up or 30 seconds whichever comes first.

After firing a new fuel filter to mine (Fram) it took a while to start, take no notice of the 5 times thing in the handbook.
Mine eventualy went after a good number of purges and keeping the throttle on trhe floor with **** loads of black smoke when it did fire.
Make sure filter is on tight enough and not letting air in.

You can be absolutely sure a loose filter will NOT let any air in.
However, it may let a whole lot of fuel OUT.

Priming and Starting a TD5 after an air ingress is a pain.

Rave says this, but where it says in 2. to wait three minutes, you carry out the throttle decking process till the squealing stops at the filter. The squealing noise is AIR in the fuel. The fuel pump sends nearly a gallon of fuel a MINUTE through to the cylinder head fuel gallery, and even at that it may take ten minutes or more to purge the air out enough to get the injectors primed and teh engine fit to run. THEN you need to turn it over on the starter for quite a while to get the crazy injectors working.

So, from RAVE ...
If the vehicle runs out of fuel, or the fuel level is so
low that the fuel system draws air into the fuel rail,
the fuel rail will need to be purged before the engine
will start. This can be achieved by following the
procedure below.
If this procedure is carried out on a vehicle that
has not run out of fuel or otherwise drawn air into
the fuel rail, it can lead to the engine flooding and
failing to start.
Purge
1. Turn the ignition switch off and wait 15
seconds.
2. Turn the ignition switch to position II and wait 3
minutes (this ensures that the fuel system
purges all the air from the fuel rail within the
cylinder head).
3. Fully depress the throttle pedal.
4. Keeping the throttle pedal fully depressed,
crank the engine.
5. As soon as engine speed exceeds 600 rev/min,
release the throttle pedal and the ignition
switch.The engine must not be cranked
continuously for more than 30 seconds at
any one time.
6. If the engine fails to start, repeat the above
procedure.

It sounds brutal, but it is common in diesels to have to keep the starter engaged for a while even though the engine is coughing and spluttering and smoking.

You should try starting an old tractor on a cold morning! One of two things will happen:
1. the engine will fire up before the battery goes flat.
2. the battery goes flat before the engine starts.
