I wrecked about five months ago and now I am ready to get back on it. The problem is that I can not get my bike to start. There is not any fluids leaking from the bike and the tank is full of gas but it will still not start. I thought that it might be the spark plugs but when I spray starter gas into the air intake it will fire but only as long as I keep spraying the igniter gas. I then thought that it was flooded so I tried opening the throttle all the way to disengage the fuel pump and burn out excess gas but that is not the issue either. I don't think that any gas is getting into the engine. When I went down it was on the right side of the bike. Also when I turn on the key I do not hear the fuel pump engage. The only thing that I can figure is that the bank angle sensor is messed up or somehow needs to be reset. I did a search for like a break down of the bike so that I could get to it but I could not find anything that would help me. None of the fuses are blown either. how can I reset the bank angle sensor, or how can i get a guide to take it out, or if you don't think that that is the issue how do I get the fuel pump going? I could really use your help on this guys!

BAS resets when you cycle the key. As long as it is int he right spot and functioning that is not your issue. Check the kill switch at your right thumb.

There is a way to short the fuel pump in a way to force it to turn on - this wouldn't be a solution but you'd be able to use it to troubleshoot. This is a test that's listed in the service manual, I'll have to check when I get home. If the pump turns on then you know the pump is okay. If the pump doesn't turn on it's defective.

But for now start with the simple things. Check the kill switch. If it's off the fuel pump will not turn on.

If the kill switch is set to run then check your fuses. The 2004-2005 had this inside the kickstand side front plastics near the front turn signal. Make sure they are all okay. If those fuses check out then check the fuses behind the battery and make sure they are also fine.

Lift your gas tank and make sure all the connections leading to the tank are still plugged in.

Edit: Just saw your year. I don't where anything is on that bike but the principles are the same. Find where your fuses are and check them. Check your kill switch, make sure everything leading to the fuel pump are plugged in.

All of the fuses are okay. And as far as I can tell everything is connected correctly so that the Fuel pump should be getting power. I think that it might have something to do with the bank angle sensor but I do not know how to access it. I am also looking for a link to get the service manual for the 2008 CBR1000RR if anybody knows a site.

Just so you know, that bank angle sensor is just a pendulum with a weight on one end and a sensor on the other. If it is stuck for some reason then it may not allow your bike to start, however this is improbable at best.

Also, on the 04-05 bikes if you remove the bank angle sensor the bike also things that the sensor is tripped so don't expect it to work if you remove the thing for troubleshooting.

If you have a multimeter you can test the BAS by checking resistance in ohms. You are not looking for any specific number, just a change in value - you should see the resistance between the two wires change as it goes from upright to 'tipped'. If it changes then it's ok. Since the bike won't run with it removed I believe the BAS simply causes a short between the two wires when the bike is upright and breaks connection between the two wires when it's sideways so it should be damn near zero ohms when upright.

here's the link with the 08 service manual.

Are you sure you've checked all the fuses?
There are two fuses actually located in the starter relay assembly. People often overlook those.

You have to pull the cover off the starter relay, to get at them.

Assuming you've now got a copy of the service manual, have a look at page 19-14.


To eliminate the bank angle sensor, disconnect it and then jumper the Green wire to the Blue/Red wire, in the vacated connector. You'll find the BAS tucked between the headlights. You'll have to pull the upper cowl to get at it.
