Tenni Diagnosis

[Orson]

On my last trip, my Tenni failed on me and I was wondering what the cognoscenti might offer as a diagnosis.

 

The bike was running fine until I stopped for gas/petrol. When I started it up again, it seemed to be running on one cylinder. I made it about half a kilometer, and then she just died Checking the fuses, I found the fuel pump fuse had blown. I replaced it with the spare fuse, but as soon as I pressed the starter, the fuel pump fuse would blow again.

 

I managed to get the bike back to Guareschi Moto where they'll hopefully make her good as new, but am wondering what you lot think caused the problem.

 

The bike sits for long periods while I toil away in Saudi. I suspect that doesn't help matters.

 

relays?

fuel pump?

bad coil?

stuck throttle body?

The same fuse powers the injectors and coils. It could be just a short cut from a scuffed cable, or the pump, a coil or an injector. Since it was running on one cylinder I'd guess coil or injector. Of those, I think statistics would point to a coil.
