Just bought an '09 big bang, my first, as a mini project that needed a good tidy and tlc.
Started ok before buying, but hasnt started since I got it back. Had a 22 error code and
I replaced the sensor, knowing that wasnt the root.

Wasnt till I tried again I heard the pump prime and it fired up, but didnt run long. Rarely
is the pump priming, but when it does it starts.
When the pump doesnt prime there is a faint high pitched whine.

Any opinions on the best fault finding path? Where to start first? I have an incling it may
may be the ignition, as I've had that with another bike. But this is the first bike I've owned
with a red key/immobiliser. Are ignition replacements as straightforward because of this?
The key is very hard to turn in the old ignition.

Thanks in anticipation.

Pump spins when 12v applied.

Chased the connections from the ignition, but although the key is v sticky, it seems to be making the right connections. 

Anyone tell me where the fuel pump relay is? To check the volts there?

Thanks

Hope that helps.

I did. The post seemed long and rambling. I have put it in a garage to be diagnosed but they are a bit clueless. Trying to find a decent mechanic/bike auto electrician in the glasgow area proving v v frustrating.

But thanks.

Over to you then Jimmy....He's up around Glasgow I believe.👍

Unfortunately I can't help. No knowledge of modern bikes electronics, and have no one to recommend, sorry 

No worries.
