Fuel pump not priming

The bike was running fine. I had it on a lift when I started it up. When switched tanks it stopped priming. The relay is not clicking on the bike, but when I tested the relay off the bike I heard it click. It is reading the right ohms. The bike is not getting fuel but it turns over like it wants to start. I don't have the Fi light on, speedo works, all lights work, and all spark plugs are brand new. It seems like the red kill switch on the handlebars isn't working? I'm finding it very hard to believe that it is the fuel pump because I can't even get a clicking sound. It is not the kickstand switch. I didn't even ride the bike, but just had it running on the lift. Like I said when switched tanks it wouldn't start. Everything is plugged in. I do have the "CHEC" on the speedo. I checked every fuse and they are good. The battery is reading 11.74. How do you check the red killswitch to make sure it is sending power to the relay? Electrical wiring Cable Gas Wire Vehicle

If you check for spark and don't have any then it's the tip over sensor. The bike wouldn't turn over if it was any of the other ones. Have you tried putting it in dealer mode or checked for codes?

No. I had a mechanic that was supposed to come and look at it, but he claims that he is booked until the 30th of this month.

The service manual and a few threads on here will show you how.

I tried the paperclip thing and nothing happened. It just says CHEC on the speedo. It doesn't pull up any codes, but I never had the Fi light if that has anything to do with it?

If you didn't have an FI light on when you checked it, it usually shows 00 as the code. But in any case, if there's no light there won't be a code.

Still no luck. I even tried another ecu. I can't get a mechanic to come check it out. Some of them won't even return my calls. I guess they hate money? The only thing left is the flasher relay, kickstand switch, tip over sensor, and all of them seem to be working. I can almost guarantee replacing these relays won't help at all. I already replaced the starter relay and the fuel pump relay and it did nothing.

Call the dealer and arrange for them to come and pick up the bike . It would cost you a little bit , but you would finally solve the problem whatever it is once they hook the bike to their computer and see what is causing it .
After all your tries and realizing that nothing have worked , that is what I would do .

I finally got a mechanic to look at it. He was baffled and it took him 3 hours to figure out the problem. He said it has a faulty ignition switch, but I haven't replaced it yet. I hope he is right?

He was wrong I guess because I put on the other ignition and the bike still won't prime.

Did you find out the cause of your problem? I am having the same exact issues.

If you have removed the tank, check that the 4 wires going tin the electrical connector under the tank for the fuel pump are all pushed into the connector tightly.
These wires will pull out of the connector easily when removing the tank.....see it happen all the time.
