hi everyone
My daughters 99 2.0hdi had been cutting out on her occasionally over the last 2 weeks and just will not start now ,I have tested a few things replaced filter run a new tempary fuel line from tank to filter housing and nailed it down to no fuel coming from rail side of hp pump [bosch system] I've undone union on pipe going to rail,Proper fuel supply right up to hp side of fuel filter housing, wondering if there is a solenoid switch which i could deactivate or replace on hp pump Any advice would be appreciated

Whilst you state that there is a "Proper fuel supply right up to hp side of fuel filter housing" is that supply under pressure? The reason I ask is that there is a 'sump pump' AKA 'primary fuel pump' in the fuel tank which is prone to failure. When the ignition is turned on prior to starting can you hear it running under the back seat? If not then give the base of the tank a good thump which may trigger it into life.

To gain access to the pump lift the O/S base of the rear seat and remove the plastic plug.

The HP pump cannot suck fuel to itself, it requires fuel to be delivered under pressure so running a separate supply line is unlikely to work.

It does sound very much like injector pump failure. I'm told this starts as cutting out followed by not starting. A Bosch specialist is probably your best bet.

Hope you get it fixed.

Personally I'd get the engine ECU read with a Citroën dedicated diagnostic tool such as a Lexia rather than use a Bosch generic diagnostic tool as the Citroën tool will be able to fully converse with the ECU, generic tools can miss out on vital information.

Other thing could be a crankcase sensor had that before on plant at work only ever the once but a lot cheaper than a fuel pump.

I had a 2.oi Hdi 110bhp in, and after changing the fuel filter the car would NOT run past 2500prm, it would then automatically stall....

It ended up being JUST the STOP solinoind on the BACK of the pump, between the pump and fuel filter..

One plug, TWO Torx bolts and it pulls out..

I swapped the unit with another from a 90bhp and it fixed the problem completely.

What I did notice on the shaft theres a TINY rubber seal.. it had a knick in it.. as the other solinoid fixed the problem Ive not done anything with the one I removed so dont actually know if the small seal was the problem...

As I had the car running again, I wasn't gonna chance any more swapping risking more ECU Faults or a non runner!

Well I was thinking that generally Citroen dealers don't know the in's and out's of the injection system. The car is probably running a Bosch ECU and components so if a Bosch specialist can't deal with it what chance does a dealership have? Also the price will probably be fairer at the specialist. Not to mention that they can actually fix the fault if they find it. The dealership will probably just change parts until they find the cure.
