Note
Cranking with the Cam sensor disconnected and running a Apexi Power FC ECU, still injects fuel.

Done this on a mates car when we swapped injectors.
No.2 Injector wasn't seating/sealed so it flooded the bore.

We took it out, re-seated it then cranked it over to blow the excess fuel out of the spark plug hole.
This was done with the crank sensor removed, but the 3 remaining injectors still connected (mechanically and electrically) and the HT leads disconnected.

Once we dried out the bore and re-assembled. It wouldn't start, well it did, just, but was running on 1 (No.2).
The 3 other bores were now flooded, due to the cranking 'with the cam sensor disconnected'.

Plugs were removed and dried for the other 3, cranked with the cam sensor 'AND' the injector connectors removed to make sure the bores were drie and we didn't re-flood No.2.

Everything refitted and it ran sweet
