any chance it could be bc of the ground wire? i have it bolted to the frame, but i didnt sand down the paint. i was thinking tht maybe its not grounding and therefor not priming? but would that throw a code at all?

That could definitely be a good possibility. Sand down the paint anywhere you have a ground wire. I'm pretty sure that it would not throw a code for that. You can always just check for continuity between your negative terminal on the battery and the wire that is supposed to be grounding, to verify if it is grounding properly. There are other possibilities such as the bank angle sensor but I would start with cleaning up or at least checking those grounds.

who do you think you are using big words like "continuity".....? Ya that sounds like a good idea. Ima go sand her down and check her out. hopefully this will solve the problem.

I had mine apart and it did the same thing. I just unhooked it from the fuel rail and pointed the end in a ratio rite turned the key on and by the second or third try it started to flow.Hooked it back up and everything was fine.

I sanded down the frame and attached the ground like its supposed to. and still not starting. Its weird, I unplugged all my lower fuel injectors, and it didnt throw a MIL code. anyone have any ideas on that? i remember last time i put her back together, i forgot to plug them in right, and it didnt start and it threw a code.

So I went out there, and it seems that every time I turn the bike on, and the kill switch is off, there is a little tick inside the fuse box (i think, either the fuse box or something near that). when the ignotion is on, and i turn the kill switch on and off, i can hear the clicking sound going off. dont know if that has anything to do with it. i also had a blown fuse. a 10A, it saiys on the fuse box that its for the horn and whatnot. dont know if thats related.

as you can see, im not so good with the eletrical stuff. any help would be awesome.
