Just come in from a very late night trying to help my friend sort a weird problem. Story goes as so :- 406 R reg 2.1TD,taken into local garage for fuel filter & cam-belt change.Nothing wrong with 406 when dropped off for work to be carried out.Telephone call this afternoon to collect car - it,s ready.Upon arrival to collect car won,t start ! Garage says will source problem & ring when sorted. Garage phones - it,s ready - now to start the car you have to pump the throttle & keep turning until she eventually starts.Obviously we complain in some style!! They reply that the troubles in the fuel pump - even though the car started spot on before filter change & cam belt.In short they don,t want to know -more like they don,t know what they,ve F.......D Up!! So we have been trying alsorts to figure out what,s wrong.It makes no sense at all - the belt was done as a precaution as my friend has just purchased the car after trying my 406 out & loved it. Has anybody any idea ? or seen this excess throttle pressing as if to prime the engine - We are at a total loss to what,s up.My mate is p....d off to say the least. Engine Guru,s please?????

Could it be air getting in the system somewhere. I had this problem on an old petrol citroen after I had a small under-bonnet fire. After this, I always had to pump the peddle about 10 times on a cold start (or after leaving it for over an hour).

Whatever it is, the garage should sort it out, but I know what garages are like, and this situation isn't the best to be in.

The garage have done something and don't realise, or have forgotton!

They may have disconnected something, possibly even a sensor, or they have not BLED the fuel filter and lines after the filter change, the older 2.1 is not self bleeding, I suspect the later.

They need it back in to sort it, my garage road tests a car BEFORE they do any work to make sure that the work they do has not affected the car in some way. This way it avoids the ''my cars worse now'' argument.

Now surely they DID NOTICE that the car started well when they were moving it into the workshop etc, someone must have started it.

A simple bleed of the fuel will sort it I reckon.

theres only 2 possibilities i can think of, either they didnt bleed the fuel filter properly, or at all, this would give the car enough diesel to the pump to drive it out of the workshop and thats it, it will NOT bleed its self and trying to start it will kill the pump as it has no lubrication, or they have messed up the injection pump timing doing the cambelt, most garages dont have a clue about diesel engines and fail to realise how critical pump timing is

The car was taken today to a diesel specialist, you couldn,t be more right
about lack of diesel engine knowledge. It turned out that the pump timing was completely out & cam timing also. It,s unbelieveable that a car that started
perfectly every time could be messed up so bad. Anyhow all is well now - she starts beautifully every time. I think the lesson here learnt is, watch where you have your car maintained. As mentioned continual use in the state it was could have cost even more if say the pump or similar gave in due to wrong setting up.
Incidentally the garage initially involved have a good reputation! You just never know eh?

Hello, where abouts are you located?

It would be useful to name and shame the garage if this is allowed, but equally it would be useful
to name the good diesel specialist who sorted this out for you!

Thanks,
Paul
