It is probably your EFI main relay which is a common problem on Honda/Acura vehicles. The sympton is usually the customer will come out and try to start their car on a hot day after it has been sitting and the car will just crank over and crank over but it will not start the engine. Sound familiar? it costs about $60 for the relay and takes 1/2 hour to replace. Good Luck!

yes he is correct, if leaving car out all day i use window shade and before i start it i open all my windows and sunroof and let it cool for a second. i also cover the sensor in the center of the dashboard.
