Starting Problem
 

It's an '05 RX8 and I just had the spark plugs, coils, battery replaced about two months ago. Recently got a new car and I was out of the state for about a month so the car sat in a non heated garage for that month. When I went to start it up today all the electronics turn on and it sounds like it has full power when its turning over but theres no firing/spark when turning the key. Any ideas?

Check battery voltage. Your battery is being used even when it sits there. Put a battery charger on it now and a trickle charger when you go away for more then a couple of weeks.

true... if you haven't turned it on in a while your battery is drained... if you have a closed garage , next time you decide to not use it , don't activate your alarm, just lock the doors manually with no alarm activation, this will help to reduce the battery from draining.. trust me I do it all the time and it works ....good luck !!!
