i have problems whit my zx9 00' , i change the spark plugs and after that won't do anything, i change the starter solenoid, and starts once but after that time won't do anything again, so i change the cdi and starts once again but after that won't do any kind of sound or start, and i change the right hand control because i figure the kill button or start button was bad ,but same thingwon't do nothing ,and new battery , please if somebody can help me, i don't have any idea whats wrong whit this bike.

 

wow, you are sure changing out parts. So what is the initial prob?
Welcome to the forums

 

yeah the wording makes it sound like the the problem either started before the sparkplug change or was caused by it.

I assume that the spark plug change was initiated by a running problem.

 

quick question where the plugs gapped to spec

 

sounds like a ground problem.like the nuetral sensor or the clutch sensor might be causing the bike not to start. when u turn on the key to all the lights come on?

 

yes the bike strated befor i change the spark plugs, the spark plugs was new from dealer, they said spark plugs was gapped to spec. and yes when i turn the key on all the the lights come on. when i change the starter solenoid the bike starts but just one time after that the bike doesn't do anything,when you push the start button. can you guystell me wher the neutral sensor and the clutch sensor are?.

 

Check your fuse block, and start following wires. Sounds like a dead short that gets "reset" with each new install. If not wiring, it might be the brain box. Has the bike ever been in a crash? That electrical stuffcan drive you insane... Good luck.

 

I DID REPLACE THE BRAIN BOX ONCE AND JUST STARTED ONCE BUT AFTER 10 MIN. GUESS WHAT, LIGTHS ON BATTERY CHARGED AND AGAIN, NOTHING NO START NO SOUND JUST LIGHTS ON, PLUS I CHANGED THE RIGHT HAND CONTROL AND SAME THING CAN YOU HELP ME GUYS? THIS IS MY FIRS BIKE SO I DONT KNOW TO MUCH ABOUT IT. THANKS

 

do you guys think could be the starter?

 

You must be pulling your hair out by now. lol Have you checked the neutral and clutch switches yet? How about the ignition switch?
