Causing the lack of fuel was the big red button, wasnt plugged in properly, this and the wire that comes off the HT Box (the HT set up that isnt HT leads) that looks a little like an earth but not 100% sure what it is, this was dirty so cleaned up and put back on.
Immobilisor light was on and still is, but I have unplugged the immobilisor.
Before I plugged the big red button in properly, when I tryed to turn the engine it would do very slowly, as if using a very low battery. With this plugged in it turns well with full fuel pressure
