Hey sometimes when i start my car i hear a humming electrical noise..possibly an exaust leak but after some checking, i dont think thats what it is.. It fluctuates when lights and other electrical appliances are turned on and off.. It comes on very rarely but is noticable when on.. possibly from back right or front left of car
Electrical whizz noise

any clues

 

what kind of fuel pump do u have....it might be that cause my Walbro 255 is audiable over my exhaust....heh

 

do you have the walbro pump installed on your car??they make the humming sound normally.

 

hrm great minds think alike...

 

Yes i doo i have walbro.. but the noise only comes on once in a while ...is it normal... ??

 

Yes, you should be able to hear the fuel pump well if you have a Walbro
