I just bought a used 2009 Zuma 125. It was working fine until it stalled while on a ride. It now only starts when giving it gas, and dies when you let off. I've checked the following: Spark plug, cap, cable, coil are all okay. Fuel Injector sprays mist. Fuel Pump primes. I will check fuel pump with starter fluid next, and check compression.

What is the issue? Bad fuel pump? Any help would be appreciated!

Here is the video of what it sounds like:

Have you taken your VIN # to your yamaha dealership to make sure the recall was ever done on the fuel pump? That's one of the 1st things i did when i got my 2009.

Thanks for the tip. No I have not taken it to a dealership yet. I tried cleaning out the fuel injector a couple days ago. It still has a hard time starting, but if I just give a little throttle for 20 seconds, it doesn't stall. Still not sure what the problem is though!

Anything that starts with gas and dies when you let of the gas start looking for a vacuum leak in the intake area
