Hi Centaur, annoyingly the fuel pump and control all tested ok, when bridged it still cuts out/F1 light comes on.
Sh8t.
One further thing I noticed is if you leave the bike at the point you would hit the starter (i.e when its ready to start with the F1 light out) the relay clicks and the F1 light comes on after a few seconds (i.e without being started).
Fuel cut off relay, I assume.
Seems something is triggering the ECU, running or not running, to cut the engine?but it does not log it as a fault.
Hurra Fixed!
I stripped back the previous loom fix and found it pretty shabby and wet. Re-soldered all the earths together there and also soldered a cable between the red and green connector from the tilt switch.
Started up straight away and problem gone. I removed the tilt switch bridge and so far it is behaving, ordered a spare switch from the breakers just in case.
It could have just been the tilt switch but I think a weak earth was contributing to the problem making it hard to spot.
Anyway thanks a ton for all the suggestions and getting me back on the road!!
