Yes I completely burn it up trying to get it started and it will not even turn like it’s froze up

Hello all again, I got the starter from the link that was posted got it in an all is good on that front. But now back to the original problem, it will not stay running here is what I’ve done.

1. Changed to gas to new gas
2. Checked the fuel pump to make sure it’s pumping it is,
3. Checked the injector with a 9volt battery and it sprays gas
4. Checked all the vacuum lines and all seem good.
5. Checked the run switch seems to work fine.

And all the other things that were posted for me to try.

Still nothing, so in saying all that I still have the air breather cover off and when I spray a little starter fluid in there it will start and run for a few seconds until that burns off.

Any other ideas?????

Any help on getting the darn starter out

Starters are a no-brainer.  There's only two types of standard Chinese starters (50cc and 150cc) and you can find them on eBay, usually less than $50.  And for each there's only two bolts holding it in place.  Remove the seat-pan to see the starter. Remove all the plastic duct work that's in the way. Look for the two starter attach bolts, undo them, and pull the starter out of the hole.  That's it.

JJ,  he has replaced the starter. See his last post. That is no longer an issue....still won't run.

It seems like it is time to look at the ECU.
IS the ECU sending signal current to the fuel injector to spray in the fuel.
Unplug the black wire at the injector, and using a multimeter probe on the two contacts in this wire -- check for a current @11V>12V coming from the ECU in this wire when trying to start.
If not, there is some possibility that there is a break in this black wire - but more likely the fault is with the ECU.

Please report back.

Beat me to it! Stig is nailing it! It runs with sray to the intake = fuel delivery problem.

@stig I took the connector off the injector, and but the black and red multimeter in the connector and tried to start and the voltage was all over the place way up and way down never stayed on just 12 volts

That injector gets an electric pulse every other revolution and your electronic meter "samples" what is on the red and black leads about every 3 milliseconds. That means the meter will show all kinds of voltages. You have a fuel delivery problem....

1) Was the high around 11>12V?
2) Is there a reading with just the key on - and no start?
I have a service support ticket created with a Kymco mechanic - and will report back your findings - please be as detailed as possible , with answers as well to questions 1 & 2.
Will relay your info on Monday. (tomorrow)

@stig when cranking the voltage jumps around but never higher than about 2.5v and with just the key on absolutely ZERO V

Thank you so much

Please confirm not a typo …."2.5V", not 12.5V?

Yes only 2.5 at most while cranking it jumped from zero 1.3 to 2.5 and in between

Is the trigger for the injector 12 or 5 vdc?
