    Need troubleshooting help please.

    Been up since 315a and on road at 415a.

    25 miles West of Spokane on Cheney offramp.

    Engine died.

    Battery voltage is 12.28V. Starter cranks, voltage drops to 10.8V. Engine won’t fire.

    I pulled fuse 5, waited 5 min, key on, switch on, 2 throttle pulls, key off. Resets TPS. No change.

    Fuel pump pressurizes upon switch on. So fuel pump sounds like it’s working.

    Fuel pump/filter/lines, battery, spark plugs all new. TBs rebuilt. New pushrods. Valves gapped. TPS reset and TBs synced perfectly.

    3/4 tank gas

    2 solid ABS lights upon switch on.

    I’m going to pull plugs and inspect.

    Any thoughts?

    Cables are solid.

    I don’t know what crank voltage should be.

    Are the cylinders getting fuel? If you turn over with plugs clipped into coil wires, is there spark?

    While the plugs are out, I would check formsparks while cranking. If no sparks, I am susPecting the HES.

    I’ll check. Also trying to get at alternator belt to see condition.

    HES is 20k old

    Alternator belt looks ok. Starter cranks engine, and alternator belt does not slip.

    Left spark plug sparks in coil on starting.

    Right spark plug sparks in coil on starting.

    Does anyone have any ideas?

    I REALLY appreciate the help.

    Thanks

    What would clogged fuel lines or fuel filter symptoms be?

    Can I test fuel flow by pulling one injector at a time and turning over to see if TBs are getting fuel?

    So I pulled injectors and started. I am getting fuel there. So that seems good

    Does anyone know if 10.8V during start is enough?

    Your spark plugs look dry in the pictures, they were pulled after cranking to start ? Some of these era bikes can have the in tank fuel lines come apart or split thus not providing adequate fuel pressure. Did you have good spray pattern and adequate volume of fuel from each injector ?

    10.8 is marginal on your cranking voltage but should do the job.

    It’s tough for me to know what adequate injector fuel flow should be. It’s definitely not 0. I just don’t know how much would be enough

    Oh—the in tank fuel lines, pump, filter and pre-screen were all just replaced.

    This leads me to think clogged fuel filter. I’m on the second tank of gas after the above work, and maybe the fuel flow is not enough. But I have spark and fuel, so it seems like it should be at least firing.

    Any thoughts on what I might check next?

    TPS voltage is still 340V—right where it should be.

    I guess maybe something to think about is why would the engine have died going 70 mph after 6 hrs of riding. Spark is there. Fuel is there. What electronically could have stopped working? Battery 12.7V. Cranks at 10.8V.

    I sat on bike and put up kickstand thinking sensor, but that didn’t work.

    Maybe I’ll try to disable kickstand sensor next. It’s turning the same way it does when the kickstand is done. So maybe that’s it

    I can’t figure that out here. Crap

    Can you look into the tank and see if fuel is moving around when the pump is running ?

    Your battery is for sure, a bit on the weak side. It had been running and it just shut down, battery voltage should be up above 13 volts at that point. It should crank and fire at 10.8 volts but you really are getting at the lower end.
    The fuel pump, as I recall, will run for 2 seconds at ignition on and it is not really an indicator of anything other than the motor is turning. I would bypass the fuel pump relay so that the pump runs full time and immediately try to start the bike. If it runs, fine, ride it home like that or to a shop.
    If no start, then I would look at the battery. A lot of the chain auto parts stores sell small jump boxes and if you happen to be near one, buy a jump box and try that. Most of the chains also sell batteries suitable for motorcycle use, they may be labeled for lawn tractors but you bike can't read so you should be OK.
    When and if you get it home or to a shop, the fuel pressure should be checked, needs to be in and around 42 PSI with the engine running, may surge up around 45 PSI prior to start.
    Sorry, I don't have any fuel flow data for checking injector flow, there may be something in the factory shop manual, I just don't have that information available. It is doubtful that both injectors would have failed at once and the motor would run, badly, on one cylinder anyway.
    This bike has be sitting a couple of years, a deteriorated fuel line is not out of the question. Again, chain auto parts stores, the proper clamps and tools would be needed as well. You may need to McGiver something to get you home.
