peugeot boxer cutting out

[alvan]

Help!
have a 2004 peugeot boxer 2.2 hdi since 18 mnths and has been brill; but then started to cut out when more power is needed ie up a hill or on exelaration;
took it to peugeot here in france; they changed the fuel filter as the code sais fuel starvation;
but no good;
injectors have been tested and been reconditioned by diesel specialist;
have changed the fuel rail pressure switch to be sure;
auto electrician has tested the fuel pump and all working, but problem still prevails if not worse now;
starts up fine, but as soon as temperature is reached it cuts out or sometimes goes into limp mode;
codes have been checked several times but no further;
over a 1000 bucks later i have to sort it out myself now;
am wanting to replace the high pressure fuel pump;
are there any manuels or guides available, or is it even possible to dismantle fuel pump without disturbing timing belt

thanks
Al

Have you changed the pressure regulator on the pump? These have a very fine filter which can block, I haven't found a way of clearing them so a replacement is usually needed. Mine is on a 2.0. engine but I think the 2.2 is similar.

Thanks for that;
had thought of that, but so far it seems i have to buy the whole unit, ie with pump; but probably worth finding a supplier for that;

I got one off ebay for not to much money but it was also clogged, some come without the filter so I ground the end off, works fine now.

If you post up the VIN we can look in service box and see what system is fitted, and if it lists the regulator separately.
