2012 dowtown starting issue

[Volcabar]

The fuel pump is heard EVERY time? Even when it won't start?

The furthest hose, that the one that looks kind of tan? If that is the one you are indicating, it is supposed to have a black plug in the end of it. Very hard to see. Must lay on your back and look up. The slang name for it is the "Puke tube." Must be drained periodically.

Yea, that one, nothing on the end of it, no plug.

Every time I turn the key the pump is heard.

No plug is not good. That tube needs to be plugged when engine is running.

Do I need a specifi plug or will anything do?

[CROSSBOLT]

Anything to stop it up will work.

Thinking more about the main problem....since you can hear the fuel pump run EVERY time you torn the key on lets the relay off the hook. Next suspect is connectivity to the injector.
What I have done with the scoots I have and have had is unplug every connector, liberally apply silicone dielectric grease to every female side of the connector and plug it back in. That cures and prevents corrosion in those metal to metal contacts. See if that works for you.

Will try that tomorrow, dont have the time today and the shops arent working now, dont know if gas station has that grease.

The dielectric grease available at auto parts stores and most Walmarts.

Heh, Im from Croatia.
Covid19, stores work until 5 pm, auto stores are not allowed to work.

[CROSSBOLT]

Ah! That does complicate things! Had the same trouble with a fellow in Greece trying to get that stuff! We will stand by for you!

[Volcabar]

Update, went to the scooter few min ago, turn the key, cant hear the pump, tried again, no pump, tried 10 times, no noise from the pump.

[CROSSBOLT]

Aha! Relay!

[Volcabar]

I just have to take the front plastic off?

[CROSSBOLT]

Yes, all the little relays except one are above and slightly behind the horn. High and low beam on left, fuel pump on right with start relay. Yours may be different so make sure.

[Volcabar]

They are different, all on the same side, but replaced it, engine is starting now, but engine light is still on when I turn it on, cant clear the code 33, is it safe to ride with engine light showing?

[CROSSBOLT]

To clear the code disconnect the battery for 30 seconds or more. You can do the same thing by pulling the 30 amp fuse for 30 seconds or more.

Yeay! Hooray!

Thank you very much Crossbolt, saved me a lot of trouble.
Where can I find the relays to buy and under what name?
Dont think kymco relay will mean much on ebay.



Disconnecting the battery didnt clear the code.
