Hello all. So, just a couple days ago, I took possession of an absolute MINT 2001 1100XX. At 13000 miles, this bike looks like it came out of a time capsule. I bought it for a steal with one caveat- the bike will not start. It cranks as strong as it should, but will not start. In the 2 days I've had it, here's what I've discovered and what I've tried-

The pump does not prime while inline, however if disconnected from its connector and jumped with the battery, it will.
All fuses check out ok, and all relays activate when removed and tested.
The pump connector receives its momentary 12v when engaging the Start/Stop Switch(as I believe it should).
I've disassembled the Start/Stop Switch Assembly and cleaned/dielectric greased all contacts.
No FI lights displaying at testing.

Sooo, with 2 days of Blackbird research, I believe I can conclude that the ECU and connectivity are good given that 12v is sent up to the pump when it should. I think I can also conclude that the pump is good, since jumping directly to a battery brings it to life. I unfortunately lack the knowledge and experience with this bike to tell what else could prevent initial priming while everything is in circuit. Bank sensor, perhaps? Something still amiss within the tank? May be worth noting, but I'm told this bike started last Fall before putting away for the Winter. The previous owner kept the bike in the house with very minimal fuel, so possibly something within the fuel pump assembly in the tank is gummed up? Anyway, thanks ahead for any thoughts suggestions?

Not sure exactly what this means.

Anyway, on a correctly functioning bike, in neutral, start/stop switch on, key on...........fuel pump should whir to life for 4-5 secs, and then go off.....not momentary.

There is a service manual somewhere on this site with wiring diagram for reference. Start/stop circuit includes start/stop handlebar switch, side stand switch, neutral switch, tip over switch. ECU needs all systems go from this to run.

Temporarily jump the fuel pump and see if she starts.

Hi Fizzy, thanks for the help! Honestly, I'm not sure the exact amount of time I got power to the pump cable, I simply recording that I got power and moved on. I've sent away for a Service manual, so will definitely be having a look at those switches. I've jumped a wire from a test battery to the unplugged pump and did get it to prime, but it sounds you're talking about jumping the pump while its in circuit to egt the bike to start- can you go into detail on how you mean? Here's the only pic I have at the moment-

To your point, I would think that if a switch or a sensor was not satisfied, I wouldnt get 12v to the pump. Am I wrong?

Not wrong.

Turn on ignition like I mentioned above, fuel pump should whir for 4-5 secs. Does this happen?

If not, disconnect 2 pin connecter at the pump and jump it with 12v and ground. It should whir to life. Then try to start normally.

Nice machine, almost too nice to ride. Once you get it running there are a few things that may need attention in light of low mileage and non use (650 miles/year).
