To find it, you'll need to consult your owner's manual. This is the most reliable source. The manual will show you a diagram of the fuse box and relay locations.
If you don't have the manual, you can:
* Check the fuse box under the hood: This is the most common location for relays. Many Aleros have a fuse box with a cover that indicates what each fuse and relay controls.
* Check the fuse box inside the car: Some vehicles also have a smaller fuse box inside the cabin, typically near the steering column or under the dashboard. This is less likely for the fuel pump relay, but worth checking.
* Search online forums: Search online forums specific to Oldsmobile Aleros (year specific if possible). Other owners may have posted pictures or descriptions of where they found their fuel pump relay.
Important Note: Before working on any electrical components, disconnect the negative battery cable to prevent accidental shorts.
