no start

Post by LukeG »



Hi guys sure would love some input here. This spring the Wing wouldn't start and I isolated no fuel coming out of petcock valve. I replaced petcock valve diaphragm and voila work for rest of summer. I haven't started the bike for about a month now and now when I attempt start after oil change, no start. So with just the fuel line coming out of the tank I am getting no fuel out as I turn over. As soon as I STOP turnover, fuel dribbles out. Any light bulbs out there?! Is fuel pump sketchy?

Put a test light on the fuel pump and repeat your test. If the fuel pump is getting power but you get no output, time to pull the pump. If no power when cranking, time to look elsewhere.

ok..........am getting 6,5V at fuel pump when cranking. Again, no fuel output at crank but a little AFTER crank. I think I read somewhere that there should be equivalent of .5 litre/per minute or so output. I am assuming 6.5V is right voltage so I guess I pull pump!

In case you do not have a service manual, here is the Fuel Pump Test procedure:

You should have 12 volts at the pump. You can do the test described in the manual Mike posted. If that passes, then you need to explore why you only have 6 volts when cranking.
BTW you might want to measure the voltage at the pump when doing the test. The Blk/Blu is the wire to the pump, and the Blk/Wht is power but via quite a few places where there could be voltage drops, so if it is not at battery voltage, that would be good to know.
A few folks have had the pump output transistor in the ECU fail, but I believe that is typically an all or nothing affair.
