Silly question, but have you run the pump by independently connecting it to a battery? Or tested the pump for continuity?

I had an issue with a car not starting. I could hear the pump was not priming. Checks showed no error codes on the ECU and the ECU was not earthing the fuel pump relay (which earths the fuel pump at max volts). Turned out the swimmer fuel pump was open circuit internally, maybe rooted brushes, and the ECU detected that.

Indeed.
Or, as on one car I got running (which had already been through two auto elecs) , a cunning kill switch.

The new ecu has had the immobilizer bypassed, but I also tried running 5v to the blue wire on the immobilizer plug.
I have checked the kill switch off it on it crank on it will.
Not having taken an 06/7 ZX10 for a run before I am not sure on the safety cut out but checked the normal stuff, plus all sensors seem to check out ok
