interference coming through radio

[Anabolic]

when I turned my radio on today & started the car, it almost sounded like i could hear my fuel pump through the radio. Any idea what would cause this? my trunk is gutted but both fuel/stereo are stock to what i know (not sure what previous owner did)
but what would cause this?
never happend before and just happend once

Do you have the hood insulation removed?

This can cause interference.

 

[Anabolic]

yes ofcourse I do.
Through the back speakers it can?

 

[Boostman1]

do you have a system in the car

 

[Anabolic]

no everything's stock, stock 460.

[Anabolic]

If it doesn't stop with good weather check your antenna cable connection. My beater Saturn had all kinds of interference and it turned out to be a loose jack and plug connection between 2 cables under the dash. I pushed the cables back together and had no problem after that. Oddly, I'd never been under the dash so vibration over time must've been the cause.

I know people have some interference like that once they install HID's. Check it out just in case if u do have a pair. Good luck.

I think I have this same issue in my wife's 04 GT and my Cobra. I haven't gotten a chance to look into it but to me it sounds like a ground issue.
