Sounds like an injector issue.

Did you fit an after market UBP if so they tend not to last long or a very noisy, a pierburg original will be silent and last 100,000 miles or more.

Hi Ravinder
Yes but they are not cheap, also best to make sure they are genuine Pierburg

I had the same thing, years ago, and it was a faulty ECM, due to having been wet at some stage in its life - but I'm guessing you've checked that...

Pierburg and TI Automotive are the OEM supplies for R75 and ZT’s if you buy a Pierburg from eurocarparts and open up the box you will find a TI Automotive pump.
also rimmers supply TI Automotive as OEM.
Many of the last 2 pump system cars from factory had TI Automotive pumps.
Work perfect 3.7bar and very quiet. Cheap aftermarket pumps sound like a swarm of bees buzzing underneath the bulkhead and often only produce circa 3.5bar
Tested so many I have lost count.

At £129 that's a significant outlay. I have heard that the problem can be relay failure and it has been suggested I should replace those first at around £8 but not sure about this. Has anyone tried this before replacing the pump?

The fuel pump relay tends to be very robust, the fuel pump relay output driver from the ECM, well that's a different kettle of fish altogether.

That is the first thing that tends to fail when an ECM has been swimming

I fitted a Ti pump to replace the original Pierburg, as it was becoming noisy, cheap aftermarket pumps are cheap for a reason........buy cheap, buy twice.
