It is perfectly reasonable for someone to post on an older thread, especially if it is the same car and same basic problem. Push button start problem on an Accord, this thread is a good place to post. Or alternately post on your own thread. 6 of one, half dozen of the other.
@Nmsims2 : First off, when you say it won't start, do you mean it cranks but doesn't pop and run? Or does does it no crank at all, that rrr rrr rrr sound. If so, does it make any sounds at all, like a click? If it is a no-crank, no click problem that is often caused by a safety switch that prevents the car from cranking if it isn't in neutral or park (if an automatic) or the clutch is depressed (if manual).
