Today I rode the bike to work and felt a little hesitation once and just assumed it was a head wind. During lunch I went to a restaurant and when I came out I went to start the bike and it fired one time and stopped. It did this a few times. Not knowing where to start on these electronic puzzles I took the cleaner off and checked the connector at the throttle body, cleaned it and put everything back on. Then I pulled the plugs and they're good, I just replaced them with some ngk plugs about three weeks ago. Tried to fire it up again and now there is no fire whatsoever, so I pulled the coil and wires off took them to a shop to have them tested and the wires were good but they couldn't check the coil. The tech there said that he had seen this problem before and said that it may be the crank sensor, so I went to the dealership and bought a new one. Got back to the bike and reinstalled coil and wires, put on the new sensor and still NOTHING. what else can I look at on it... There is no check engine light but I'm stumped.... Please guys any help would be greatly appreciated!!!
The battery is a low hanging fruit to check. Make sure the terminals are tight and/or have it tested. The bikes do strange things when the battery is suspect.
Do you all think it may be the battery even though the bike was cranking strong?
You did not give that info in your original post...if its still cranking strong then I would say its not the battery.
If you have an ECM tuning module, like a Power Commander, I would remove that and see what happens...also, check to see if the wires going into the stator on the front part of the primary cover did not come loose. It has a rubber boot...i have seen those cause problems too.
by pass the switch on the console or the one on the bars? when I turn the switch on the console with the switch on the handle bars on, I can hear the pump prime and stop as usual. it just stumps me on how im not getting any spark. the bike has 32,000 miles, is it common for the coil to go bad about this mileage range? im willing to swap the coil, but I want to be sure. also is there a way to diagnose or test the coil on my own?
and sorry guys that I didn't mention that the bike was cranking strong when all this started happening....
