Modern Vespa

Pretty much I was riding it, stopped for about 20 mins, got back on it to it to ride away, and it wouldnt start.
I checked the plug to find no spark, I replaced the plug and still no spark. I found there was no live feed to the plug, so could it be what im guessing is the ignition coil? (red, white and green wire go into it? Ht lead comes out of it?)

You can test the coil with an ohm meter (see service manual). Sometimes they just die.

I had a similar experience. I have two et2's so I was able to swap the CDI Coil and determine that that was in fact my problem before ordering another. Sounds to me like that could be your problem. You might want to try screwing the spark plug wire into the coil to make sure there is good contact. The new one will not come with a new spark plug wire. You will reuse your old one unless you order one of those too.

The cdi unit i ordered came today, fitted it and still no spark. Only thing is the old one had an earth lead and the new one doesnt. Would that make a difference?

The one I replaced had a ground wire and the one I replaced it w had a ground wire. Both of the et2's I own have ground wires on the CDI. Thats all I can tell you.

Yes. There are two CDIs that are used. You need to get the one that matches the one you took out. Every ZAPC16 ET2 I've seen takes the CDI with a ground wire.
