car starts only when it wants

I would check the ignition too..mainly the ignition switch....my best friend had that same problem with his gf's 95 civic hb...we took the ignition switch out and sure enough it was wore out, after alot of brainstorming, we figured out why it wore out....his gf had alot of keys on her key ring..and from the vibration of driving and shit and the weight of the keys yanking down constantly....it just wore it out....with that info we contacted our "hookup" at a local honda dealship and they agreed that that actually does happen...so..maybe thats what happened in this situation...who knows...either way....it might have just worn out...don't necessarily need a ton of keys...that just speeds the process.....well theres my 2 cents.....ok maybe 10...
