Looking for the fuel pump on a 2000 oldsmobile aurora...

Most modern cars have the pump in the fuel tank. If you look under the car at the back of the tank you will likely see a circular plug with 2 or 3 hoses and wires coming out, that is the pump.

Hi Sandra , What do you mean by fuel pump release switch ? There is no such thing on Oldsmobile's .

It is a special pump and goes by a specific part number not a size. Any auto parts store can look up the pump for you.

Could be a lot of things. Get the engine scanned for any codes. Look at fuel trim and O2 sensors, etc. Could be bad gas, dirty filter, fuel pump. A common issue on these engines is the plenum connecting the throttle body to the intake cracks. Causes rough idling/stalling. Also look at air filter, MAS Air Flow sensor. But reading your fuel trim values should help here.

According to my parts guide, the fuel pump for your 97 Olds Aurora fits only that and the 97 Buick Riviera's and nothing else. The pump for a 99 Park avenue comes up as a different part number. Hope this helps!

Does it crank ok? if so its not the starter, More likely an fuel pump or an passive anti theft concern

The GM 1995 Aurora repair manual, says to use the access hole under the carpet in the back right corner of the trunk. You are best to buy a new fuel sender locking nut or ring at the dealer for about $8.


Forgot to add this - to relieve the fuel pressure, just use the press the center of valve on the fuel rail (for pressure testing) and a rag to catch the dribble. Really no big deal.

Make sure disconnect the battery cables too

looking at the notes i have on it... you have to drop the tank to change it

The good news first!!
No need to drop fuel tank!!
Lift carpet from trunk ... just in front & a little to the right of spare wheel well is an access cover. When screws and cover are removed you have complete access to top of tank with pump and sender assembly mounted below a twist off clamp ring. When replacing Delphi fuel pump unit make sure you also replace gasket.
The bad news!!!
New pump unit over $300!!! ... try junk yards.

Look on page 6-70 of your owners manual. It is listed under Engine Accessories Belt
