Troubleshooting electrical/fuel problem
This past weekend my '02 1100S (36k, single spark) stalled out 2 blocks from home on the way back from a short 5 mile ride. Granted the bike is just about due for a valve adjustment, but something about the stall didn't feel right. The engine didn't even try to idle, it just went to sleep as I dropped the bike in neutral for a stop sign. The engine did start back up hesitantly, and was good enough to run me back home, but on the way, I did notice that the instument cluster illumination was a little dim, and the left turn signal indicator was glowing faintly. So I guess there was something electrical going on (duh).
I parked the bike and looked for obvious signs of a short (smell, burnt wires, etc.) but didn't see anything. Fuses are all good. Turned the ingnition on, and heard the fuel pump run for a second, as usual. Dash was brightly illuminated and the ghost in the turn signal loop was gone too. Tried turning it over with no luck. Then I see fuel dripping from the exhaust headers at the connector at the cross-over pipe in front of the alternator cover.??
I pulled the plugs, and both were black. And dripping with fuel. Got a fresh set of plugs and confirmed spark at both sides. Tried starting again with no luck.
So my question is, what would cause the injection system to dump fuel into the cylinders to the point where it would overflow into the exhaust? Is this probably a symptom of a burnt ECU?
Any thoughts?
Thanks,
Anthony
