paul1804 Posted March 1 Share Posted March 1 (edited) I have a Yamaha scooter, Grand Filano 125cc which cranks over as it should in the mornings but the engine does not fire. After quite a few attempts it finally starts and runs as it should. After sitting all day come evening the same problem, when the engine is warm it starts straight up so only when the engine is cold. It is fuel injected so I am thinking its either the fuel feed pump or the fuel injection system malfunctioning. The battery, starter etc is working fine, I replaced the air filter and spark plug a few months ago and its serviced regularly, once running it performs as it should. Anyone have this issue with a Yamaha scooter, Mio, Fino, Filano etc??? Edited March 1 by paul1804 Link to comment Share on other sites More sharing options...

Have the same problem occasionally but only in the morning, kick start doesn't work, not sure if it is the switch in the stand but sometimes if I put it down and up a couple of times it will start, also if it doesn't start on the first crank I turn the key off and then back on then it usually starts mine is a 2016 Link to comment Share on other sites More sharing options...

Jimjim1 Posted March 2 Share Posted March 2 Sounds to me that you have a leak in the fuel delivery system which allows air in over night and you have to crank the engine until the fuel is pushed to the engine clearing the air and allowing the engine to start, the earlier suggestion of a leaky injector could be correct so you should check all fuel line connection's.

anyone Posted March 2 Share Posted March 2 Maybe it's the ignition coil. After I changed mine it became much better. There could be a dozen reasons... Link to comment Share on other sites More sharing options...
ChipButty Posted March 2 Share Posted March 2 We used to have that problem with our old Fino especially if it had been standing for a couple of days, Last week I bought a new one, the new ones don't have a kick start on them, Link to comment Share on other sites More sharing options...

You can hear it when you turn the key. Then it stops. Then OK. Link to comment Share on other sites More sharing options...
