I have a 2006 Z1000 that I bought new and have never had any problems with until now. Recently, when I tried to start it, the starter would turn the motor over and over and it wouldn't fire up. I let it sit for a while and then it started right up. It happened a few more times with it starting some days and others not at all. I never smell raw fuel while cranking it when it doesn't start. I keep it on a Battery Tender Plus and still use the original battery that reads 13.50 volts when at a full charge. I bought a Kawasaki Service Manual and tried to diagnose the problem. I pulled the fuel tank and ran 12 volts to the fuel pump and it pumped plenty of fuel. I tested the white fuel pump connector on the bike when the ignition is first turned on and I get 0 volts. I then checked the fuel pump relay and it doesn't click at all when the ignition is switched on. I swapped it out with another and tested both relays and they are both good. I checked the "tip over kill" box and it was a bit corroded, but cleaned up nice. Still no power to the relay and fuel pump. I pulled the ECU and all connectors are clean. I tried the self-diagnosis lead under the seat and didn't get any error codes from the FI light. I pulled both the camshaft and crankshaft position sensors and neither had any metal filings on them...
Any idea what is going on with my Z1000??
Thanks in advance for any help!

I am assuming you have checked all fuses, and the wiring diagram for fuseable links? Just keep back tracking from where you have no power till you find juice....then you will know where your problem is.

Ok cool, thanks for the quick reply! I checked all of the fuses and they are good. I also checked the 30 amp main on the right side with the red cover over it. The four prongs inside the connector had some corrosion and I cleaned them. I traced and did a continuity test to check for breaks on all wires back from both the fuel pump connector and the fuel pump relay. It's just odd that the Fuel Injection initializes and the starter cranks but, the only thing that is cut off is the fuel pump power. Very strange... and frustrating of course.

One of the first things I tried with a bit of luck when it didn't fire up was to remove the Camshaft Position Sensor and wipe off any possible metal residue or filings. I put it back in and it fired up. I took it for a ride and all was well.... later that night it refused to fire up.
So today I decided to order one for $70.00. Hope it does the trick!

Today I replaced the Camshaft Position Sensor with a new one and my Z1000 still won't start. There is still no power to the fuel pump!?!

For some reason, I didn't hear the fuel injection initialize when I turned the ignition on. I traced it to a blown 15 amp fuse under the seat to the left inside the white fuse holder which also carries a spare fuse onboard. This is not in the fuse box, it is the ECU fuse. Strange... I swapped out to the new fuse and the FI initialized, but still won't start.

What should I try next?

Thanks for the advice notabike! I will pull apart the kill switch and check it out. I will post the results as soon as I do it.

UGHHHH....I'm in the same boat with the same problem! Please tell me you figured this out. The self diagnosis gave me error code 11 and 32. But I don't know how to fix the problem. The manual says replace throttle body assembly...you gotta be frickin kidding me. It has to be just a sensor problem...HELP!

check for...

i had the same problem with my 07. after buying stoopid amounts of parts and non working i tried a little actual troubleshooting... there is a ground wire under the tank that vibrated loose. it is connected to the frame so start following wires from the tank connection to the frame and see if you find anything loose. hopefully you won't end up like me with an abundance of expensive parts you didn't need to buy because of something simple like a loose wire. good luck! oh and the shop didn't figure it out either...

Please tell me you figured it out? I just replaced the entire wiring harness trying to fix this same problem, to no avail. I haven't been able to ride since last summer. I'm about to order a new fuel pump, I'm hoping that will finally do it
