OK, I have kind of an odd situation in which my fuel pump (I think) has been acting up, particularly when it is warm outside. It makes a whistling sound, like a teapot. Here is the sound (my car in the video):

I had actually asked this question once before:

http://www.autogeekonline.net/forum/off-topic/40024-mechanical-question.html


So here's some info:

Make: Oldsmobile
Model: Cutlass Ciera SL
Year: 1995
Mileage: 161,000+
Engine: 3.1L V6


Mechanical info:

* 7/16/2010 131,695 miles
Fuel pump, strainer, and fuel filter replaced


* 8/1/2011 143,213 miles
Fuel pump and filter replaced


* 7/19/2012 153,610 miles
Fuel pump and strainer replaced
Fuel filter replaced
Fuel tank sending unit replaced


Which brings us to today. My car now has over 161,000 miles on it. It was a rather warm day today - around 80* or so. Had to take the car out today to go somewhere; when I got back home, it was making that whistle. I have not had to pay for each replacement fuel pump and subsequent labor (it was under warranty), so this isn't like my mechanic is trying to pull a fast one. I think he is as frustrated with this as I am. Thoughts? Do I just need to call my local GM dealer and see if I can get an OEM fuel pump? What else might be causing it to consistently fail like this?
 
What brand of pump is he using? Is the filter after the pump or is it the sock that attaches to the pump?
 
Sounds like a faulty fuel pump. I would go OEM or try and take back the one in the car now and switch it out. I don't trust aftermarket fuel pumps, it is hit and miss.

Did your mechanic check the fuel pump relay?
 
Ethanol gas can lossen up stufin the tank and cause problems in older vehicles. That the government for you

Shane you have been battling that problem for a long time....IIRC this is the same problem that you had before.

Go OEM trust me on this one.

The fuel filter is always after the pump....whether mechanical of electrical. The sock( as reffered to as the strainer is attched to the pump itself) is normally in the fuel tank itself, to which rarely causes problems.

The fuel pump relay (which is for todays type Electric pumps) is sometimes a real good place to look for fuel problems......BUT if the vehical is running the relay is working, as in Shanes case here.

Relays work or they don't.......there are a lot inputs required for a relay to work ie ,battery power ,ignition power and a ground or multipal grounds....and ultimately one output(as in this case power to the pump).

Shane your Car is running.....just making that noise Again and if it quit after each pump replacement......Go back to oem and put another 161,000 miles on that great looking Ciera.
 
make sure baffle in gas tank is not comming apart inside gas tank and buy delphia fuel pump from napa auto parts
 
What's the update on your status Shane?

If it does come out to be another faulty fuel pump you have in the car, replace with OEM only.
