HDi Xantia 110 non starter

andmcit · Post by **andmcit** » 04 Sep 2008, 20:11

Pal of mine dropped in to his local GSF counter this evening and now has a
turning over but very dead diesel Xantia. It's a non immobilised car and it
hasnt been through any floods or even big puddles and was running fine 10
minutes earlier!? The k light is on during turning over. Usedto occasionally
drop into k light limp mode randomly before a year lay up.

Suggestions!? Flywheel sensor? Ignition switch?

check & see if the low pressure fuel pump in the tank is priming up with the ignition on, if no give the underside of the tank a bang as you crank it.

second step if the 1st fails is to spray some easystart up the intake (after the airflow meter) & see if it runs on that.

Is easystart a good idea after what I've seen and discussed elsewhere
on the forum? Can the priming fuel feed be verified from disconnection
of a pipe on the engine if the pump is silent in operation?

Yes just take off the feed pipe at the fuel filter (think its the one with the white end).
As for the easy start im not saying to start running the car on it, its just used as a quick check to see if its a fuel problem or not. without having diagnostic gear to read the live data & paramiters from the ECU you are quite limited to what you can do.

Well done wheeler!!

Tap on the tank got the car started again!! Top man, I salute you
(my pal does too!!).

So what is this pump that my pal needs then - is it similar to the petrol pump
in the neck of the tank accessed through the flap under the rear seat? Are
these hideously expensive new or even available second hand and are they
110hp model specific?

Is this the offending item in question:

N18375 FUEL LIFT PUMP(IN TANK) XAN HDI 65.00

Its an easy enough job, accessed fron under the rear seat just like the petrol fuel pumps, get a new seal aswell, sometimes they can expand & you cant get them back on.

May have got the car started, but now my pal is having difficulty
stopping the engine now!! Is this purely electrical or is it down to
the low pressure pump? Is there a king of choking lever on the
pump that stems the flow of diesel as per older Cit Diesels?

Update from my pal!!
Apparently, the cause of non stoppage of the engine was the Vacuum pipe.
All working again (for now...)

which vaccum pipe would that be then ? sounds strange.

My thoughts exactly! I'll try and fill in more details tomorrow.

Hi Andrew,
could you sort out what was the cause?

Certainly Karel - silly my not finishing the thread by giving the punchline!

The sender low pressure pump in the throat of the fuel tank was the culprit
for the starting issues. Whilst the replacement from GSF wasn't a cheap fix
at over £130BGBP it got the car running reliably again so possibly not a
horrible cost to set things right again.

The only other issue was disconnecting the pipes which have sprung grips
of 'fast release' joints which took some getting to work!!

All good now though!

Hi Andrew
and thanks for the reply. I myself have changed just the electric pump, not the whole in-tank-unit. We (east europeans) can get the pump separately, but "Made in Poland", what speaks for itself. The polish one is notably louder than the original. But it was definitely cheaper, about 55 GBP only. Had to change it as I found copper swarf from the worn down motor collector in the diesel filter housing.

Yep, the "fast release" joints are fast only if you know, how to open them
