for anyone interested, post my shadow running out of fuel it failed to start again. I assumed it had a fuel cut off, here's what I have discovered.
Fuel cut is supposed to only xist on USA cars, it is located next to the fuel pump.
I have a fuel cut off on my UK spec car, dunno y but I do.
Checked that, nothing.
On good advise of B Man, I checked the relays, ineresting discovery, no power.
Got the guy in who designed the electrical architecture of the car, after about 90 seconds, he had the pumps working.
He diagnosed a fault in between the Ign switch and the fuse box.
transpires that during the cold spell we had coincidently when the fuel ran out, the constant turning over of the engine before numb nuts here realised I had no fuel, the bus bar between the live feeds on the ign switch had cracked, this bar is plastic coated so you can't even see the bar.
He has taken it away to repair it, back tomorrow when hopefully I will be up and running again.
