i have a cbr600rr 04, i cant figure out what the problem is. The fuel pump wont turn on and the headlights wont turn on/the meter wont illuminate but turns on. The fuses,relays,ecu are good, the fuel pump works, also the bank angle sensor is getting readings. i also have reviewed the wiring harness and have not yet found a problem yet. This started the day i layed my bike down, i picked it up and drove home. I stopped it in my driveway and it just wouldnt start again. im not quite sure what to do, does anyone have any suggestions?

 

If the fuel pump works, and the fuel pump relay is good, are they getting power? Did you test voltage before these loads? It also seems like the crash has something to do with this so inspect areas of damage..... common area to miss is in the steering lock area for pinched wires due to the handle bars floppin around.... Let us know!

 

Have you checked continuity on your relays? I know you said they were good, but recheck your engine stop relay and starter relay. There should not continuity all the time. With your headlight not working, I think one of your relays is faulty. I would suspect your engine start relay first, since when that relay is triggered, it shuts off your headlight. Just test it and make sure there is only contiunity when on it when your pressing your start button, otherwise, replace it.

Im not sure how you checked them, but just listening for them to click is not enough, you will need to test them properly.

 

ok thanks guys, im going to go through all the relays and wiring harness more thoroughly, and see. could this have somthing to do with my ignition?

 

ok so problem solved, it was a green and white wire that has came loose on the wiring harness, now the wire bypasses the harness, and the bike seems t be working fine now.
