that sounds like a problem ive read a lot about on the forum, and had happen to me once, except when i turned mine off and turned it back on, it started right up and had no trouble after that, seemed to be the case with others that ive read about, did you make sure you were fully in park when you tried to start the vx again? if you were still in drive when you tried to start it, that would cause the engine to do absolutely nothing when you tried to turn it over.. always start looking at the small things first, fuses, being in the right gear, battery etc
