I havent had my car for very long (2 months or so)
but the pump does whine. I dont know if it was ever swapped out as there are quite a few mods done to it.
Just wasnt sure if this is common in vettes

No, it was a problem for the first year, and the fix was a technical service bulletin by GM...if your car is a 97 it would have a sticker from the dealership showing the free repair was completed...

Mine whines when it gets real hot, like on a long trip in the summer. It is worse when the fuel starts to get low. Normally back home it's not loud or a problem.

From what I've heard, yes, there is some whining that can be heard from the drivers seat. You can add a layer of insulation to the back of the seat wall under the carpet, that should help cut down it a little. The fuel pump is directly behind your lower back and I hear mine from day one.. If you get a new muffler system, like I did (FlowMaster) then open the window and you will only hear music... Enjoy the ride.

What year is your vette? Can you describe the issue a little more?

Do you hear it when you turn the iginition switch to the 'on' position?
Does it happen every time you drive your vette?
Does it get worse as you drive long distances?
Does it go away after driving for a while?
Does it get louder as the fuel level drops in the tank?
Do you hear any variences in the sound when you press the gas, turn on your blinker or turn on the radio?
Have you put your ear to the car and listened for where it is the loudest?

Check this link out. This is what has been happening to mine:

Also, if you do a search for "fuel pump" in the tech section you will find a TON of other threads about the noisy fuel pump. It is a common issue.

From what I have read it is common among the 97-98 years. GM redesigned it in 99 and should be quieter but it still happens in the 99-04 year models. It doesnt mean the pump is going out. Mine just started making the noise about 2 weeks ago. I'm having it checked just to be safe.

Whines for just a second when start up is all is normal. But from all the other parts on the car. I cant hear it no more at all.

Yes, all of the below, again it's not a very loud whine, but you can hear it if you are at a stop sign and kinda focus on it. Yes it goes up in noise with acceleration, and when signaling, it goes up and down with the voltage drop. It's livable in my vette, yours may be very loud. Could be a worn fuel pump. Try insulating the pump itself if you can.

Do you hear it when you turn the iginition switch to the 'on' position? .. a little
Does it happen every time you drive your vette?....Yes
Does it get worse as you drive long distances?.... No, same constant
Does it go away after driving for a while?.....No
Does it get louder as the fuel level drops in the tank?.... No
Do you hear any variences in the sound when you press the gas, turn on your blinker or turn on the radio?.. Yes on blinker, no because the radio over rides the noise.
Have you put your ear to the car and listened for where it is the loudest?... Yes, behind the driver seat lower left hip area against the back wall under the carpet.

Hope that helps.. You have what most of us have.. maybe louder than most. See a dealer if you can't stand that noise... Good luck and enjoy the ride (with the radio on).

I have a '98 and mine whines after driving it for on the highway for a while. In town driving doesn't seem make it change pitch. Hopefully it's just a nuisance and won't leave me stranded!

rtpassini

Mine is a 98

i dont drive it a lot. maybe every other weekend or so. but from what i recall, its constant.
it never changes pitch even with blinker or radio. It doesnt bother me. Just wondering if its something I should be careful for. I've only filled it up twice and both times I have added techron.

Razzputon

By no means am I an expert on this but from all the posts I have read your issue doesnt sounds like a fuel pump. Sounds more like a grounding issue.

Everything I listed in your quote should be the opposite of your answers. I would like to hear from more seasoned Vette owners though.

It wouldn't hurt to change the fuel filter in case it's the original, after 50,000 miles they tend to restrict flow making the pump work harder and louder.

did you pop the hood yet and look for the recall stickers? if that car was ever in for service the dealer would have automatically switched out the bad pump for the improved design....ALL early C5s have qualified for the free replacement....LOOK FOR THE STICKER...USUALLY NEAR THE RADIATOR!!!!!!!!!!!!!!!!!!!

rtpassini

just looked. the only sticker I saw was for the serpentine belt orientation

is there a database for all recalls that should have been done so I know if theres something else I can have swapped out? or to check if mine was done already?

$$$frumnuttin'

your dealer can check for you in the database for your VIN...all work performed on the car since it was sold to the public is there, including any TSB recalls....you will probably learn more than you want to know...

This just happened to me on my trip to Bowling Green... Pulled off the interstate after driving from Indianapolis and there was a whine. Did a search on here about fuel pump whine as soon as I got in the hotel and found that on hot days or long drives this isn't uncommon. However, mine goes away when not driving long distances in hot weather.

Artak

so bought a c5 couple of days ago and I am having the same issue, should I be worried? What did you end up doing???

Fcar 98

There is not a problem with the fuel pump. Mine is a 98 and has whined since day one. That’s 23 years.

Gunfighter77

Slight fuel pump whine is usually normal. Especially depending on year.

If it gets worse it's usually a sign your fuel pump is on it's way out.

ztheusa

Fuel pump whine is totally normal, especially on early C5s

If you can hear fuel pump whine you aren't driving fast enough.
