I have a '98 Civic EX and the other day I noticed that when the car was off, it would make a strange 'buzzing' sound every 60 seconds or so, and it would last for about 3 seconds. Couldn't figure out where it was coming from or what it could be. If anyone knows what this might be I'd appreciate it.

 

it didnt sound like your fan coming on and off? or was it more of an electric sound?

 

its probably your fuel pump going on / off.

my friend has a similar problem with his fuel pump relay, get it checked out.

 

ok well i just went out there and its not doing it any more... i just wanted to make sure it wasn't anything too serious cause i've never heard it do that before... i'm gettin' an oil change soon and will mention it to them and see what they say... thanks for the help!
