2008 CBR600 won't start...

I wrecked on it on the left side about a year and a half ago, but it mainly just messed up the gas tank (wore a hole through the side) and the left handlebars (and the mirrors).
Then I sold it to someone who wanted to fix it up, but he couldn't make the payments, so I got back a "fixed up" bike, which was in working order and seemed to run well.

I let it sit over the winter, and this spring, I rode it around a few miles, came home, and now it won't turn back on.

At first, it would crank, but not turn over. Now, the battery is dead, so it just clicks, but when you try to turn it on while it's being jumped by a car (engine off), it cranks again, but still doesn't turn over.

I also don't hear the fuel pump priming.

I've checked the 30W fuse, but that doesn't look damaged or blown. I've also purchased a new battery, but it just cranked, and didn't turn over like the other battery, so I took that one back. I also tried turning the kill switch off and on several times with no luck.

If you guys have some suggestions, they are more than welcome!

Try to start it while holding the throttle wide open yes wide open that will stop the flooding of the fuel injectors it will take a few trials so be patient and make sure that the battery is fully charged go ahead give it a go any questions or problems post them here



If it doesn't challange you it won't change you

As soon as my wife gets home with the car (~7 hours from now), I'll put the jumper cables on and try this. I'll post the results immediately afterwards. Thanks!

Make sure the car engine is off and hold the throttle steady once it starts then within a few minutes let it go and let the bike's own idle keep it running do not rev it or it will die again and will be even harder to start again once the fan turns on 220 F degrees you can shut it off

I hooked it up to the car and tried jumping it with the throttle wide open, but it still never turned over. I tried around 5 times before giving up. I also still don't hear the fuel pump turning on when I turn the key to the "ON" position, like I used to be able to. I think my next step is to try cleaning the contacts inside the killswitch... I don't know anything about this stuff, so wish me luck. I'll update when I have results.

There are several things you can look at, killswitch would be the first and easiest, as they do get dirty and temperamental sometimes. Take it apart and clean it, make sure the contacts are touching too. Could be fuel delivery as well. I would bet its more electrical than mechanical though. Check fuses, plugs, pinched wires (if the guy was "fixing it" he may have put it together incorrectly), anything that may be out of the ordinary. Also, check the starter relay. Try starting the bike by jumping the relay. If it turns over, at least you know your relay is acting up.

Life's too short. Have fun.
