My wife's 2005 Honda was working fine one day the next she tried to start it and it acted like the battery was dead, We charged it and jumped it off and it started and she drove it a few miles , turned it off and the problem returned now we can't get it to jump off when you turn the key the lights blink and you hear a clicking and buzz but the starter will not ingage? Anyone know what's going on?

It's possible the battery is bad, won't hold a charge, and needs replacing. It was likely a 3-year battery to begin with. There's a good chance the car will start, if you replace the battery.

It's best to never jump a modern-day car--it's too easy to seriously damage the ECM and other electrical components.

My battery charger says the battery is at 100% and will not start charging

. Honda starter motors are very reliable--it's hard to believe there would be anything wrong with yours, especially since it's so new.

. Most auto part stores will test batteries for free--there might be something funky going on with yours.

. Test all under-hood and under-dash fuses with a test light or multimeter:
