Few days ago my mates TD wouldnt start. We knew the fuel pump was a bit dickey, and this was on the cards for this weekend to inspect / change this.

Unfortunately yesterday it wouldnt start.
This, we put down to the tank being below 20litres, so today we investigated / sourced and fitted a new TD fuel pump.
The swirl pot and filter was cleaned. Some crud was evident, but not more than I've seen on pics here before.

The new pump was tested by ourselves before fitting.

Unfortunately the same starting issue remains. It is JUST barely firing for a split second before cutting out. Just the traditional ker-chuff-chuff-ker-chuff-chuff.....
It was turned over for over ten seconds, to ensure fuel had got to the injectors.
Small weep at the fuel filter in the engine bay, so diesel is definitely getting through.

I'm sensing an immobiliser issue. We have only one key. If it were a V6, i'd say crank sensor at fault. Is the diesel just as likely to have the legendary dead crank sensor starting issue?

The battery has been off, has something gone wrong electronics/immobiliser-wise?


Thanks, as ever, in advance!

An addendum:

His "My Naff Code Reader" system refers to the immobiliser being 'active'  when key is in, on accessory position. Can anyone confirm that this is normal?

It may be nothing to do with it but if it's weeping at the fuel filter it may be worth sorting that, then bleed the system by loosening an injector pipe and crank the engine until fuel spurts out and (in an ideal world) it fires up. Then tighten the injector pipe.
I've seen them start and run fine with a leak on the top bolt, but it's an easy enough job, so worth a try at least.

AS he says.
If the imobiliser is on the management light will flash whilst cranking and you wont get the ivor the engine kerr chuff

Ivor the engine kerchuff


May have that on my headstone 


Thanks for that peoples...I had suspicions that the immobiliser wouldnt let the engine crank. I was kind of thinking 'whats the worst case scenario' (ie: immobiliser screwed, car dead forever) then work backwards, in severity, if you see what I mean?


Suggested he try disconnecting the fuel nuts, allow fuel to spurt out, thanks to Turk, Ian D and hoofing it.
Also code reader suggesting the glowplug relay at fault, so have suggested he look at glowplug relay.

On these theres a fuse on top of the glow plug relay that looks just like a piece of metal(and not like  an average fuse)

[Agemo]

Charlie, can you let us know which fuse this is?  I have just looked on mine (Facelift) but can't recognise it.

[charlie]

on top of relay there is two screws with what looks like a piece of metal going between the screws,   the metal is the fuse

[Agemo]

Hmmm, not seen one of those. I will have another look in the morning, thanks. 

[charlie]

THe fuse is an 80 amp one,If you disconnect the battery then unscrew the two screw then lift the piece of metal(fuse) off ,all will become clear

[Agemo]

OK mate, thanks. 

[Seth]

Stating the obvious here maybe, but due to the recent cold weather, the glow-plugs could be on their way out perhaps?

Have you tried giving 'em a few 'glows' before attempting to start it?
 

[robg1984]

Thanks for all the help guys(it was my car that this refers to ) it was an airlock in the injector pipes and nothing too serious thank god shes now bled and running like a beauty
once again thanks

and AS I said...    

Only speaking from personal experience tho'.  I've done it myself !     Cleaned out my swirl pot and changed the pump, then spent ages cranking it over before thinking about what I had done since it last ran and then it dawned on me.
