What fault codes have you got? Could it be an injector issue? 

hi thanks for the reply the fault code is p0087

That code is definitely low fuel pressure but being as you  have already replaced the HPFP the only other thing it can be is the low pressure pump in the fuel tank under the back seat its a common problem as it is struggling to supply the high pressure pump when you accelerate hard.
