I have actually fixed this today (was on here to update!)
The fault was the IMV on the pump, breaking down when hot.
The odd thing was that it would sometimes start, but run at say 650-750rpm, with alt light on etc, obviously due to the lack of fuel.
What I need is a sealed rail test kit desperately.
Unfortunately I don't have the funds available, but its way up there on my priorities!
