What does it mean when I hear my fuel pump whining when my turn signal is on? They whine in unison, and it is really annoying. And when one of my bulbs went out, you know how the flash goes from normal to really fast to let you know you're losing a bulb, anyway, when it was like that you could hear the fuel pump whine with the faster flash too. Whats up with that?

 

LOL i get the same thing..... dont worry LOL.

 

do you have an aftermarket audio system? if there is a bad ground anywhere, it will do that for certain things, i had a bad ground on my component amp and when i turned my lights on my speakers would whine... not saying that i isn't the Fuel pump, but make sure it is. turn your blinker on and see if it's coming from the fuel pump area or the speaker area. if it is the speaker(s) just go through your wiring and make sure all the grounds are solid.

 

Its normal man im sure of it.

 

yeah its def the fuel pump.

dont have a sound system.

normals good enough for me. thanks.

 

You beat me to posting this topic. I have a walboro pump dont know wut kind but can hear it whistle when all sound is off but with the turn signal and stuff on it goes with it. LOL just annoying.
