So as far as I can tell lift pump in tank is not running , would this have caused engine to stop and run intermittently or should injector pump have been able to pull fuel through?
Either way it is now a non starter , will pm Andy c to try and source new pump ,unless anyone has a proven used one kicking about?
Have just put new boots on it  otherwise may have called it a day I think

Yes indeed, in my experience!

Before releasing the 4 retaining clips mentioned, it'll be necessary to release the 'ribbed' pipe:


Said pipe is released by PRESSING the horse-shoe retaining clip forwards - the pipe will then release from the T-piece, and allow the complete pump assembly to be lifted clear of the swirl-chamber. You'll also need to release the feed wiring connector (blue/red wires) as in:


At this point KEEP THE UNIT WELL CLEAR OF ANY CONDUCTABLE SURFACE, and connect a test lamp across the connector, then get an assistant to turn-on the ignition.
Said test-lamp should illuminate (and indicate no electrical supply problem).
OBVIOUSLY, BE VERY CAREFUL WHILST DOING THIS TEST, AS YOU HAVE A TANK OF FUEL IN THE IMMEDIATE VICINITY!

If the foregoing does indeed point to a defective in-tank pump, I'd recommend a genuine Vx replacement.
Part number for pump is 90509674, and it'll set you back around 120 bucks!

Also advise removing and/or thoroughly cleaning the swirl-chamber and tank plus fitting a new fuel filter.
