Having replaced the camshaft sensor, and tested its voltage I'm satisfied that the fault is not with this component.
So I replaced the ECU but again to no avail which left me with removing the wiring loom and testing it end to end - from the block connector for the camshaft sensor to the ECU block pins.
There is continuity for all three wires so next step is starter solenoid and starter motor
