I seem to have an odd problem with my 2013 Zuma 125 all of a sudden. It started about a month ago I took it out for a ride and it did not fire like it should on the first start. The starter motor turns over but it just does not ignite and start. I tried 3 times and on the 4th I pinned the throttle and it started it right up. Seemed fine for about a month and then all of a sudden it did it again yesterday. Once started it idles and runs perfectly normal. Seems to restart no problem as long as the engine is still plenty hot. I thought maybe it was because it has been sitting because of poor weather so I took it out this morning. I thought it would fire first time but it did it again this morning. In order to get it to fire I had to pin the throttle again. Then it got worse. Even though it ran fine I was at my folks house for 30 minutes and went to leave. This time it would not start no matter what I did. This time I reset the ECU and it fired first crank after resetting the ECU. I stopped for gas and filled it up. It was about a quarter tank before of stabilized gas put in back in February. Not fresh gas but not exactly old either. It started first hit on the starter no problem but then the motor was still plenty hot. My next stop was at the dealer service department since I have about 2 weeks left on my warranty. They documented it and set up an appointment for next Tuesday if I need it. They said to ride it around for a few days and if it does it again bring it in on Tuesday and they will sort it under warranty. I told them about how earlier in the day it did not want to start at all without resetting the ECU. So we let it sit for 30 minutes and went to start it but of coarse it started on first hit of the starter. The service writer said it may be likely that the ECU reset actually corrected the problem and try it for a few days and see what happens. He also mentioned that it sounds like the fuel pump issue the 09's had but stated he had to replace a few of them on later years as well. Also had to do an ECU replacement on one but that one was totally dead. He thought it was one of those 2 things. Basically its behaving a lot like a carbed scooter with auto choke issues but these are fuel injected. Really they should start on first hit of the starter button every time. Now its sitting in the garage for the night and I will see what happens tomorrow. Hopefully it starts without issue and the ECU reset fixed it. I actually posted this yesterday by mistake in the wrong forum. I am about to head out on my SH150i for fuel and then when I get back I will try the Zuma again.
