Why does this indicate that it's not the Lift Pump?!
That sounds typical of lift pump to me - the lift pump cannot supply enough fuel under load, therefore the HP pump hasn't got enough fuel, therefore the rail pressure drops and it cuts...
Change the LP pump.
Way I see it? The LP pump is the most COMMON item to fail on these cars, not yet have I seen a stage 1 or OEM HDi have issues with the HP pump, stage 2s will sometimes show up a HP pump being a little weak, but it's 99% of the time the lift pump causing the issue.
It's also a £70 fix - not £500+ for a new CR pump, then cambelt off and back on (therefore preferably a new cambelt and tensioners)... You can do a HP pump on the cheap, but you're asking for problems in the future.
