R32 Making Whining Noise

[sama1500]

hey guys

so last night i was driving around and out of nowhere this loud whining noise started happening and doesnt seem to want to stop. Wasnt thrashing the car or anything just came out of nowhere really. the noise doesnt seem to change when i do anything in the car (revving, accelerating, neutral etc) except for when i turn my lights on/off the pitch changes, noise is coming from the rear of the car underneath it as far as i can tell, have a link with a video of the sound, someone please tell me whats going on?

Link isnt working.

Fuel pump?

Sounds electrical going by your post and fuel pumps are known to get noisy when on their last legs.

im hoping it is the fuel pump as i plan on upgrading anyway, hoping its not something expensive like the diff, ill reupload the video hold on

Diff.

[Ben C34]

Seriously dude. Cars not moving so can't be the diff.

Fuel pump

first time i searched whining noises everything came up diff so i was worried so i thought i'd double check here with a video, so its definitely the fuel pump then? im thinking of going walbro 255 would this be a good choice? in terms of power i dont plan on much, around the 200rwkw mark

Fair enough . for reference if the diff isn't turning it can't make a noise.

To confirm pump, does it make th noise when you turn the ignition on after the car has been off for 30 seconds or so(without starting the car)

If yes it's definitely the pump. If only with the car on it would be engine or clutch related.

so to test what you're saying i should have the car running, turn it off, wait 30 seconds and then turn the key to the position right before the position where it starts the car?

[sama1500]

keep in mind this only started happening last night so the pump (hoping) might only be starting to go bad idk if this will affect your test or not

[Ben C34]

Don't need to start then stop the car. Just turn ignition yo on after car has been off for a while. The fuel pump will turn on for a few seconds (doesn't do iy if car was just turned off, which is why I said wait 30 seconds)

[sama1500]

yeah it makes the noise when i do that, so its definitely fuel pump in that case, pretty happy about that as i was going to upgrade this week anyway, time for a walbro 255

[Ben C34]

Well that was good timing!
