Hi Liam,
I've changed both the pressure sensor and regulator but one thing I haven't checked is the wiring going to both.. I've found a few helpful posts on checking these with a multimeter which I'm going to do later.
Another post mentioned clamping the fuel return from the fuel rail temporarily to see if this builds the pressure which makes sense and something I'll try.. At least then I'm kinda ruling things out.
Really appreciate all your thoughts and comments, feel free to add anymore things to check, try and test before I just sell up for spares and repair.
Thanks Gary
