Ok I bought a ninja 636 that was dropped the other day. I went to go look at the bike and it started up and ran great I loaded it up brought it home and it sputter starts for one second then stops or it won’t start at all. I notice when the FI light is on it will turn but no sputter start. Any ideas need help asap ---

It may or may not be throwing a code, you’d have to try pulling one to see. That would be a good start. No lights were on when you first looked at it correct? ---

No that I noticed. The bike will only sputter start when the FI light is off. How do u check the codes? Someone told me it could be the tilt sensor but I thought that resets when u turn the bike upright I hear a little ball in the sensor when I give it a slight tap. Also when it sputter starts and I go to try to rev it to keep it running that is also when the FI light will go on when I touch the throttle. ---

I actually have never pulled a code before on a bike so I’m not sure how that would work. Have you disconnected the battery at all? That could reset the ECU and maybe give you a clean slate to start with. ---

Check the wiring, could be a bad ground or something damaged from when it was dropped. Otherwise, I’d suggest checking the plugs and it might not be a bad idea to change them even if they look good. After that, maybe coil packs? Also, how many times have you tried starting it? Engine could be flooded if you’ve tried cranking it enough times. ---

I’ve never done this before, but taken from kawiforums here’s how to pull codes. It’s possible that you won’t pull a code at all. The only way you can pull a code is if the FI light is on and stays on while the bike is running. But since yours isn’t running we can’t know for sure if it’s throwing a code or not. > There is a way of doing a diagnostics check on the bike and reading the service codes that the ECU is putting out.

I tried afew times to start it won’t then after a few times it will do the sputter thing. But will the flood make the light flash or will plug I know the FI light is for the fuel injection ---

Yeah the FI light does stand for fuel injection but it also pretty much doubles as a CEL. If the bike is running and it stays on, then that’s it’s way of telling you there’s a code being thrown. What mods are done to the bike? That could possibly help in the troubleshooting. ---

Yeah has oil. I tried to start a few it won’t but then it will do the sputter thing after a few timesm will a flood or plugs make the FI light come cause I know that for fuel injection. Also I heard of the light comming on for emissions but 03 didn’t have emission ---

Also when it sputter starts and I go to try to **rev it to keep it running that is also when the FI light will go on when I touch the throttle**. The more I’m thinking about this now, I bet it is throwing a code since the light comes on only when it’s running. If you’re hearing the ball in the tip over sensor, then that SHOULD be ok. Although I’ve also heard of situations when this was not the case. When you turn the ignition to ON, does everything work as it should (fuel pump primes, exhaust servo motor whirrs)? Which side did the bike go down on? ---

mine had a loose positive wire on the battery and the FI light was on, tightened it up and it fired right up. this is probably not your problem but worth a shot… EDIT: all my lights were on because it was just turned to ignition on durrrr ---

And again that comes back to pulling the code. Spark plugs wouldn’t be a bad idea, but having that code would give you a good indication of the problem. [Next page](https://forums.speedlife.net/t/03-ninja-636-help/156923.md?page=2)
