Vibrating noise when car is off?

[tm123]

So theres this light buzzing/vibrating noise after i turn my car off and be sitting there i will hear it
it is coming from the rear i think its the fuel pump but it doesnt sound like it
it stays on for about 5 seconds stops for about 15 seconds then does it again
WHILE my car is off and the keys out of the ignition
im not sure what it is but it concerns me
please comment on what it could be or if your cb7 does it

Haha.. I bet it's your antenna motor.

Either that, or a midget with a dildo in the trunk.

Hahaha, odly enough, mine does basically the same thing. its a faint buzzing/humming noise... i cant pinpoint it, but mine kina sounds like its coming from the engine bay, like a relay or something.

hah thats funny i was thinkin at least SOMEONE would have the same noise
it might be the antenna motor, but my antenna isnt hooked up...
and it does it more than twice

Could be a couple things. Blower motor slowing down, antenna motor trying to retract the antenna (that's if ur still works lol) Fuel pump turning off (hard to hear tho).

Next time before u shut the car off, pop the hood and have someone listen for it. I dont believe it's anything to be worried about, unless ur having electrical or performance issues. good luck

thanks man
im not havin any problems only that i am getting crappy gas mileage
and this is why i posted the question cuz i thought it was my fuel pump pumpin fuel when my car was off wastin my gas
but there isnt any problems drives fine i jus need to do some things to make my gas mileage better a 5 speed swap would help lol

mine did that after i replaced the motor after the first start when i turned off the car i heard like a humming noise but it was coming from the intake so decided to just feel around the intake to see if i could feel any vibration and the only thing i felt vibrating was the IACV and it stopped, but like johnz826 said pop your hood open and check
good luck

well i pinpointed it
the noise is comin from the fuel pump area
stays on and off at least 5 minutes after my car is off
is this a faulty fuel pump? or electrical

I know the sound you are talking about. Mine does the same thing and it's been doing it for over 7 years so I wouldn't worry about it. I always assumed it was just the fuel system purging itself after shut down or something.

[tm123]

well im kinda worried about it
i get horrible mpg and i think this is causing it
one time i had a half tank when i went to bed and woke up with little more than a quarter

Antennae motor working. Even if it's not going up and down the motor often keeps working. On my car, after a day of driving in really hot weather I've observed my radiator fans working a good 5 mins after I turn the car off.

[tm123]

nope not the antenna i put my hand on it and it didnt make a noise or anything
im just gonna change the fuel pump and see if it still does it...

[tm123]

forreal
mines the only accord on this whole website that does it how convenient

my 6th gen does that. idk what it is. 4th gen has never done it.

i've heard it do it once an hour before. or just randomly hours after i've driven it.

i'm thinking it has no effect on gas mileage, i get pretty good gas mileage.

i've noticed it really only does it when it's hot outside. it could be some sort of fuel pressure relief, but that's just a guess. later.
