Electrical problems, Im almost out of ideas.
I have a 05 zx10r i have had it sine new, Its got 9k miles, I used to work on these for a living. This one has me stumped. Before i tear it completely apart maybe some has run into this same issue.
It will start sometimes but most of the time it fires up for a second and then immediately cuts off, But it will normally start after a couple tries and runs great for 5-10 mins then it will cut off, No F1 Light, nothing abnormal. The only think i noticed was odd is sometimes the fuel pump will prime then a second or so later it will run the prime cycle again and sometimes if i flip the kill switch it will not prime the pump until i turn the key off and back on.
When it cuts off the fuel pump is still running and runs for 4-5 seconds then stops like it is supposed to. It seems like a fuel pump but it checks good. It has to be electrical.
Things i have checked,
Fuel pressure and volume, Its got 43-44 psi running and it puts out 120ml of fuel in 4 seconds, Also when it was hard to start it still had rock solid fuel pressure.
Kill switch is good, I took it apart and cleaned the contacts also cleaned the connection under the nose at the plugs, It has 0 ohms resistance through the switch and the connector is good.
I took apart and cleaned the ignition switch connector its got good voltage where it is supposed to and low resistance through the plug. 6.5 volts to the gray wire.
The tip over switch is functioning properly, Also That would through a code but it is not.
Almost all other sensors are monitored by the ECM and its got no codes.
Any ideas before i pull everything one by one and spend hours tracking it down? I have never ran across one of these bikes that had similar symptoms in my 15 years of working on them.
