06 600rr, streetfightered a long time ago. I lost my keys at some point this winter so I replaced my ignition because it was cheaper. The bike sat for a couple months before I got around to replacing it. The battery is good, (tender), started fine before when I had my key, and its been garaged since. My issue now is that fuel pump won't come on, everything else is apparently fine it lights up and cranks, I've switched the relays around, checked the wires, and I get no power to the fuel pump relay when I turn the key, kill switch is fine, all fuses are good, bas is fine, I just can't track down where the issue is, and why there is no power going to the fuel pump relay.

any help would be greatly appreciated.

Im going to guess and say you bought a 03 ignition from ebay and it's got the diode in it....thus not giving the correct voltage to the ecu to turn the fuel pump on. Only way to check is open the bottom of the switch and look for the diode or meter the voltage with the key on

What should the voltage be? and can I replace the diode? If so where would I get a replacement?

Thanks alot, not sure what else it could be.

You don't want the zener diode if you have an 03-04 ignition, open the bottom of the key cylinder and see if it looks like this. If it does you need to get rid of the diode. You want 12v going to the fuel pump not 9v.

took the ignition back off, I neglected to say that the ignition I installed is an aftermarket cheapo knockoff, so guess that is my problem. no diode, i get 12v not 9v, but still not working. Guess thats what I get for buying the cheapest part possible.

Now I am confused again. from some research on the 05-06, because I don't need a diode and there are only 2 wires coming from the ignition, My set up should work, I've read posts about guys that replace the keyed ignition with a simple toggle switch for their race bikes and that was good enough, so I am still unsure where my issue stems from.

ECM??????
Ecm powers the relay to the fuel pump. If you can manually trigger the fuel pump relay then that is your problem. T

how would I go about manually triggering the relay? I have no power to it at all.

thanks again for all the help.

make sure your run/stop relay is turning on.....if it's not the fuel relay will never turn on

3 relays on the left side(stator side) fan is blue - brown is fuel - not sure what color is the run stop

Problem solved!

apparently my issue was all 3 relays were bad. I bypassed both the run/stop and the fuel pump, I thought by moving the relays around it ruled out a bad relay, and I only ever bypassed one relay at a time before, so I just bypassed run stop, no fuel pump. Then I bypassed just the fuel pump relay, no fuel pump.

As Stated earlier, my bike is streetfightered (see below) this left my relays exposed to the elements, It must have rained on them at some point before I garaged the bike, which led to them breaking. There was only a little corrosion on the pins but I didn't think about what it looked like inside the relays, I am assuming that they are corroded inside as well.

lesson learned make sure all my electronics are weatherproofed, now that the fairings are gone.
