HP can't drag fuel through 
That's why it has a lift pump :p
Remember - the ECU is looking for 3bar or so in the rail before it'll allow the car to start... If it's not getting that, it won't start - that's why you have to get the engine speed going so that the HP pump starts generating enough combined with the lift pump - then as soon as you ask for any more than idle or just revving on the spot - it'll just cut out as the LP isn't supplying enough fuel to keep with demand.
I'd go straight for LP pump if that were me.
