low fuel pressure problem.2001 110 hdi. ive already changed the pump in the tank in november but now i have very low pressure at fuel rail.ecu checked out ok.any one else had this problem?wiring problem or high pressure fuel pump????

fuel pressure sensor? Main pump failure? A leak? A blockage?

had it checked today ............ high pressure pump buggered :cry: loads off money

What a Bummer

What did they do to determine the HP pump was worn?

I had heard that if your low pressure fuel pump goes you should change all the fuel lines, fuel filter and housing and fuel tank too, otherwise the bits from the tank pump kill the high pressure pump

It allways seems to be the 110 bhp that suffers from fuel pump faliure, never the 90?

Also a nice tank full of Unleaded does nothing to help the pump(s).

On some cars you might just get away with it if your quick, but the damage is done, the pump will still fail later on.

Tis a real shame the HP pump is so expensive, it won't be long before a pump failure will effectively write the car off

the pump has to be removed and checked on a fancy machine,should be a couple of hundred psi,someone told me about cleaning the pipes but i would think thats the case if the pump starts to break up i think i'll do mine anyway just to be sure
