Modern Vespa

Two weeks ago, my Ves 300 GTS Super started one day and the next day, when I went to start it, it wouldn't start. Battery had been very recently replaced, and the lights on the dash were on. I turned the kill switch on and off a couple of times, still wouldn't work.

Today, 2 weeks later, I tried to start it and it started fine. Rode it for a half hour, and parked it. Went out an hour later and it would not start.

Any ideas?

Thanks.

What model year is your 300? It might be subject to the fuel pump recall if it's nine or ten years old.

By 'wouldn't start' I assume you mean it turns over but doesn't fire up.

It is a 2010 model with about 8000 miles on it. Sorry I wasn't clear. It would not even turn over, even though there was power to the lights and instruments on the dashboard. Doesn't seem like a fuel pump issue, but it could be.

Was the brake light on? There is an interlock that prevents the bike from starting unless you are squeezing the brake lever.

Yes. Had the left brake on with the key turned on. Did not see if the brake light was on.

Not the fuel pump then.

Check kill switch!
Check brake light comes on
Check all fuses

Can you hear the fuel pump at switch-on? If not, swap out the 'injection loads' relay.

If the fuel pump whirrs for two secs at switch-on, check the starter relay.

Thanks! I will try those and let you all know what happens.

Try the other brake, left side switch could be malfunctioning.
