2002 Bonny Noise?

When I start my car there is this noise that goes on for about 5 seconds in the rear of my car and then stops. It does this every time with out fail. It never goes any longer and never any louder. I start the car, it makes the noise and that is it. Do you think it may be a shock leveling system?

If you have ALC that is the compressor leveling the car on start up. Key on, sit on the trunk see if the same thing occurs.

Yes!. When I put the key at ON it did the same thing as when I start the engine. What am I supposed to do now?

Nothing, it is working.

I have never heard the noise before a few weeks ago. I guess that bothers me. Any advise???

Open the trunk have someonre turn the key on see if the noise is coming from the alc compressor if so, as I said 2x, it's normal.

It might be the electric fuel pump you hear.
