Hi.
I'm suffering from an engine starting problem for my YP 250,
and was happy to find this site for sharing my problem.

The symptom is that, while the starter motor is working,
the engine doesn't start up and two LEDs (I-S and ASSIST) are continuously blinking.

To better describe the symptom, I've recorded what is going on during the ignition:
https://www.dropbox.com/s/r7w0b5va8f8hzbe/2014-06-15 22.53.44.mp4

As a matter of fact, about 8 months ago, I had the same problem, and changed the ECM unit (which costed about $1100).
For a while, it was okay, and now I have the same problem, and I'm afraid I have to pay the same amount every year...

So, I would appreciate very much if anyone can guess or provide any information for me to get around this problem.
Thank you in advance.
