Thread: Td5 suddenly dying.

Driving along the freeway and all is going very well and it suddenly stops - no power, no dash warning lights - nada.

No coughing or spluttering or surging.
No faults logged in nanocom.
Unable to restart despite a few purge cycles.

Fuel pump has been replaced - no difference.
Red plug cleaned out and injector loom replaced less than 500km ago. No oil in ECU.

My feelings are that it isn't an injector issue as it's extremely unlikely that all injectors would fail in the same way at the same time. That the mechanic has been able to get it going and take it for a test drive during which it carked it again also makes me think it's not an injector fault. I don't think it's a fuelling issue due to the lack of surging, coughing or spluttering. I also don't think it's a crank position sensor as there are no faults logged as read by Nanocom.

The mechanic (who I have no faith in - see the thread in the D2 forum about not going back to dealers) is at a loss and is fumbling around in the dark - he's convinced that it's injector based and I'm equally convinced that it's not. It's behaving in EXACTLY the same manner as our old Hyundai did when its CPS died.

The question is, learned friends, what are the possibilities ?

Ignition switch?

Do you mean it has no power to the dash??

First place to check is all body earths, that the fuse box under the dash isn't corroded from leaking windscreen, the inertia switch on the firewall isnt corroded in the plug, the eiring plug for the CPS isnt full of oil.....

So no codes at all?? Noisy or missing crank signal, engine speed missing, or topside electrical failure codes?

No. I mean there are no warning lights. Dash lights are on, tacho and speedo both report what they should - engine revs and speed decaying as we coast to a stop.

Nope. No codes at all. Nanocom stubbornly reports no faults logged.
The fuse box is good - no corrosion.
Dunno about the inertia switch - should be investigated methinks. Thanks.

Hmmm. Just been told the it needs new flame rings. What are they ? Are they the injector copper washers ?

Sorry for the angry tone - I don't mean it to come across that way - it's just that I've never heard of Flame Rings and can't find a reference to them in RAVE.

I'm guessing the copper injector washers are what he means, probably trying to name them differently to cover for being useless, couple of things , when it cuts out or won't restart are the live values showing any revs , if no then cps or plug / shielding problem could be to blame,
When purging if the washers are shot , the fuel pump will cavitate
Has numb nuts fitted the fuel hoses the right way round ( top fitting is supply )
Have they plugged the injector harness back in properly?
I'm assuming it never had this problem before the work.

Quite possibly.

Yes.

No sounds of cavitation.

I'm assuming yes and yes as the car ran perfectly OK after the injector replacement for a few km.

I'm assuming it never had this problem before the work.

have a look at the "Never EVER am I going to a dealer again!!!" thread in the Disco 2 forum.
The car was running perfectly when I took it in for a simple head replacement due to rising oil levels which they reckon was due to a cracked head. There's been a litany of screw ups since then.
