Thanks for all the replies. Let me try and work my way through all the above
1. I did try and run with fuel cap open and it made no difference.
2. My test on the fuel pump was by taking the tank off and connected a spare battery to it to check that it was pumping fuel at a good rate. I have no idea how to measure this or any of the other sensors as described above.
3. I was told that the clicking sound could be a sub throttle sensor so I replaced the throttle bodies as I believe these sensors are sset in the factory and cant just be replaced.
4. As per a link I was sent I checked for error codes on the FI light and found 4 errors:
a) 1 long 1 short - Main throttle sensor
b) 1 long 2 short - Inlet air pressure sensor
c) 3 long 1 short - Vehicle down sensor
d) 3 long 2 short - Sub throttle sensor

I dont know if these are old codes that need to be reset or if these are current problems.

How could all these things go at once??

As mentioned I tried 2 other ECU units as well as two other multi function relay units

I have taken a video of the bike starting and cutting out. Oh, I also timed it and it cuts out after 8 seconds each time.

Lastly, I also took a video of the flashing FI error codes. As soon as I figure out how to post these videos I will do so.
