A 100 ohm resistor between 12v and the grey cable going to pin 46 on the ecu ( there is nothing connected into it on immobiliser models ) and it started for the first time in 6 months...

Have you checked that it's not the fuel pump itself that is not working?
Yes I can get the fuel pump to work when I send a neg on the pin from the ecu to the fuel pump relay...something is stopping the ecu from creating the neg from the ecu...I have read on the USA forums that from the ignition ...

Man I've tried everything, it now has a new wiring harness, new ecu, new relay box (all USA)....there is no F1 flashing fault codes, I have checked input voltages on most of the ecu pins (fall over switch, butterfly valve, throttle sensors etc etc).
The damn thing turns over fine but the fuel pump ...

I'm not sure mate but I've got my hands on a USA wiring harness and they are identical to the Australian harness. It's something simple I'm sure it is. I've eliminated many things including the ecu relay box, the fall over switch etc..

It's taken a while but my US ecu turned up yesterday, popped it in and I have solved the F1 flashing light problem but the fuel pump isn't priming when the kill switch is closed...now understanding why you said ecu AND wiring harness..

Yes that had crossed my mind..I'm just picking up a secondhand amp this afternoon after putting my faith in the diagnostic code...fingers crossed

Thanks Glen..that's not a bad idea...In fact it's a brilliant idea. Now that I have soldered the cut cables would simply a US ecu work on the existing loom.

I have a 2004 zx10r track bike. My house was broken into last week and for some bizarre reason the perps removed the left hand fairing and cut through all the wiring. I have painstakingly resoldered the cuts and replaced the blown 15a ecu fuse.
Obviously it won't start, the F1 light blinks ...
