I have a 2004 Hayabusa and when I turn the key on the fuel pump comes on and stays on. I have flashed the ECU several times in the past, and I don't know if that is the problem or not. I replaced the fuel pump relay and it still continues to run. When it first started, I had S-2000 injectors in it so I put the stock ones back in with no changes.
Any thoughts?
Thanks,
Dave
