Bx 17TD Stalling

Neortic95 · Post by **Neortic95** » Sat Dec 02, 2006 2:34 pm

Hi to all, This is my first visit to your forum and hoping that somone has an idea for me.

I Have a 17TD estate 1993 which has coverd 187,000 miles. I is in perfect mechanical condition. Starts first time every time uses no water, little oil, dosent smoke and always returns 50+ mpg. I used to be a citroen specialist about 7 years ago so I know the BX very well but..... About six months ago it developed a hunting at idle. This was interemitent and once warm went away so I ignored it. Two weeks ago I went on a 2000 mile round trip to Scotland on holiday and it performed perfectly. The next day on my return it cut out every time I stoped at a junction. The revs drop off and it cuts out almost every time. It always restarts and there are no other symptoms. It has a Lucas pump. Today I have tried everything I can think of to trace the cause and have come to the conclusion it is the pump. But has anyone else had this problem ??? and has anyone got a Good secondhand pump for sale. I have checked the Timming, checked and ajusted all the idle/cold start levers ( the cold start works fine) and ive used a gravity tank to eliminate any possible air in fuel issues but nothing has any great effect. I am reluctant to replace the pump as it performs so well otherwise so if anyone can come up with anthing I would be most greatfull.

One of my old BX tds developed a stalling at junctions habit which turned out to be water in the fuel, have you checked the fuel filter? I had water in the fuel pump too which I got rid of by using an additive which makes water/diesel miscible. when one of my roto pumps failed the car was impossible to start without a tow and leaked through the front seal behind the pulley.

Have you checked all rubber supply and return/leakoff pipes? And all unions on the pump and injectors?

Is the connection/electrical feed to the stop soleniod ok? Is the stop soleniod itself ok?

Does the stalling happen when the is stationary or just when coming to a stop? How much fuel is in the tank when the problem is present? Try filling it right up to see if it makes any difference - I've heard the baffle in the fuel tank can disintegrate...

I used to have a Lucas pump fitted but the fuelling device on the front of the pump which controls extra fuel during boost started to leak, I assume the diaghram or a seal has failed. If yours is ok you could swap them over (don't know if its that simple).

If it is off use to you its yours for nowt but bear in mind that it has also done about 180K.
Thats my two penny worth and can think of nowt else!!

Welcome by the way, there are so many helpful and knowledgeable people on here so hopefully you'll get better!!

Thanks As far as I know all the pipes and everything is could but I did bypass all the supply side with a gravity tank and it made no odds. I have fitted a new filter and yes it used to happen a few months ago when the fuel light came on but that was very rare once in a blue moon but it does it all the time now. I would be interested it the pump you have BX Bandit thankyou if you are willing to post it I will pay just let me know how much Thanks.

hi there,
well i would check pump timing fuel mix if poss. also partially blocked injectors? fuel filter a bit clogged up! can be a million things. but i wouldnt think the pump itself would be at fault, though i may be wrong but i think the mechanical pump either works or not.

The roto-diesel has a specific anti-stall device which is adjustable. Have you set this to the correct specs as set out in Haynes diesel book?

Thanks for all the help I have just bought some fuel additive and tomorrow I will check the ajustment of the antistall and let you know how I get on.

This is interesting.

Does everybody remember when i had a problem with my primer unit on my TZD?

I changed what i can only assume was the original fuel filter on my TZD. Afterwards the car wouldn't start because it was getting air in the fuel system. It turned out the primer unit diaphragm had split.

I got a new unit off ebay for about 25quid. It did solve the starting problem but now everytime i start the car the engine is hunting slightly. Its irritating more than anything.

The replacement primer wasnt a genuine Delphi/Rotodiesel unit and i reckon its sub-standard (certainly looks cr4p). If i go round a corner and boot the throttle it just goes flat until the car has levelled out and then it goes again.

Once warmed up the car is fine at idle but still has a problem round hard corners at speed.

Thanks everybody problem is now solved. I adjusted the anti stall (dont know why I didnt do that before) and have put some fuel additve in. No further problems.

Ian, if you mean the black `bulb` type affair I bought a brand new genuine Citroen one not too long ago. I think it was about £17.00 inc. VAT from local Cit dealer.

You could retrofit the squeezy bulb in line on an older car with the plunger top on the fuel filter, I have managed to cure air leaks on a plunger top type filter with judicious application of silicone, it was not too good for bleeding the system after that though, I used to replace the filter element at the top of a long steep hill and use the descent to bleed it
