Bike electrical issue

Yeah its been done mate. The reason I now think it may be the alarm is because the fuel pump won't even prime now but while the ignition is on occasionally you can hear the alarm clicking repeatedly as if it was being turned on and off over and over and it's the same as how the fuel pump kept priming over and over in a row. You couldn't hear the alarm clicking before because of the fuel pump. So it could be a fault with the alarm to the ignition. So that's the next step this week.

It must be very frustrating Rattler, I hope you manage to pinpoint the fault 

4 months off the road Simbo. We've got some very knowledgeable guys in our club but this has baffled everyone.

Ok looks like we have found the issue. The ECM wasn't giving an earth to the fuel pump relay or something like that. There has been a temporary fix but need to check if it is the ECM. It's a long shot but don't suppose anyone has a spare ECM I could borrow just to test it?

Sorry mate, can't help you there 

Any luck with fixing the bike Rattler?

It's going back to my mates on Sunday. I'm confident it will get fixed then.
It's was our clubs rally last weekend so been mega busy.

My bike is sorted. Turned out to be the least likely cause...the ECU. For what ever reason it wasn't communicating with the fuel pump relay properly. I bought a second hand ECU off eBay for 60 quid and after my mate checked the wiring for shorts connected it and it's fine now :)

Good to hear its sorted...been a worrying time I should think.

Glad its sorted, must of been a real pain in the arse

Glad it's sorted Rattler must have been a real head scratcher that one 

Glad to got it sorted Rattler,and the fact that you posted the problem and cure for others.

Virtually everything was tested lol and a lot of research was done trying to find similar problems and I found a site where a guy with a gixr had the exact same issue. So from that we focused on the ECU but my mate wanted to cinform the wiring wasn't shorting and causing the issue first.

My word what a bloody job that has been, really pleased you found the culprit though.

Glad you got it sorted and your mate sounds pretty savvy, was a sound precaution to check for shorts etc before fitting new ecu ...

Does the alarm have an immobiliser - maybe that's iffy ?

My mate had bypassed the immobiliser part of the alarm.

I feel such a dick - for some reason I'd missed the posting that said you'd sorted it - & all the subsequent postings !!  I'm blaming it on "system error" .  Glad you got it sorted - must have been a nightmare
