Silly thought.

All back in business now.

A final check over and a BSI reset then a ten mile burn up at 60/70mph and it's as sweet as a nut, all the fault code have disappeared and the EML is off.

Don't know what all the fuss was about, we all knew you would get it sorted

Which bit fixed it Gibbo

The replacement HP Pump
The replacement Pressure sensor

or

put the diag stuff aside, bled the system out right up to the injectors .

or all three

I can't be sure Neil, it might have been any one of the many electronic bits on the pump or the fuel rail or the glow plug system or even just a bloody minded ECU.

Oh what a sickly sweet conclusion! I was hoping for a definitive answer to my Xantia HDi non-start.

I think I have to next go down the pump exchange route.

Did you ever check any of the wiring out Gibbo2286? I ask because I've crawled all over the wiring in mine and the insulation looks very aged and almost pitted. Perhaps this is the price of living in a diesel environment. Wires feel stiff to a few choice components but resistances check out fine so probably not corroded.

I think maybe you should do as I did, forget the diagnostics and try to get the thing bled right up to the injectors,

I think that mine was trapped air in the system between the hp pump and the injectors so not letting the pressure rise enough to fire them.

I bled mine by disconnecting the injector pipes one at a time and using a hand pump to suck up the fuel until it was clear of air right up to there, then it fired up with a shot of Easy-Start and kept going, not missed a beat since.
