Suddenly stopped running whilst out riding. Cranks over. Has spark. Fuel pump seems to come on when ignition turn on. Tried removing tank cap in case of venting problem. Recent valve check, fuel filter, throttle body balance, & new battery at Triumph dealer. Ran ok for the season. Fuses ok. Nothing else electrical not working. Bike is low milage. Any ideas. I see other similar threads & will peruse them for ideas too.
Crank it for a while from cold, don't cook the starter motor, then view the spark plug electrodes and post a picture.
It might be worth checking the wiring where it passes the right hand side of the headstock. Check for exposed or broken wires due to rubbing.
Yeh I know about that I have jiggled 'em around to see if any thing happens. The black insulation around them is good. I had put washers under the little bracket to give the harness some room move as this was a warning back when they were new.
On a bike with EFI, a sudden stop like it could be ignition or fuel, excluding some mechanical failure like a dropped valve etc which would be obvious. After cranking the engine as Eldon has suggested and if the plugs look dry, disconnect the fuel line to the injectors at the inline connector, hold it over a container and briefly turn on the ignition/fuel pump to see if there is fuel flow. It could be quite high pressure so be prepared.
