Sometimes when I attempt to start my 2001 Honda Odyssey, the starter doesn't turn when the key in the ignition is turned to the start position (there's absolutely no sound); none of the normal dashboard lights illuminates; and the clock and radio apparently lose power (clock resets to 12:00 and radio anti-theft code must be entered before the radio will operate). So far, the vehicle has eventually started with all indications normal. The first time I encountered this, I moved the gearshift out of park and then returned it to park and the vehicle started normally. No work has been done under the hood recently. The battery is four years old; there's no corrosion evident on its terminals; and the leads seem sercurely connected to the terminals.

 

go have the battery and charging system checked while it's on the vehicle....

still free at autozone or advance auto parts

 

How old is the battery? Do the headlights shine brightly if turned on (briefly) when this happens.

But based on your last comment....

You may have a sticky neutral switch - if clunking the shift lever out and back in to "P" a few times fixes it then that is absolutely the problem. They are easy to replace.

Try moving the lever to 'N' too.
