* Under the hood in the fuse box: This is the most common location. The fuse box is typically located near the battery. Look for a relay with markings that indicate it's for the fuel pump or fuel injection. The relay itself might be labeled, or you may need to consult your owner's manual or a wiring diagram to identify it.
* Under the dash: Less common, but possible, especially if the car has an additional fuse box under the dash.
To find it:
1. Consult your owner's manual: This is the best place to start. It will show you the location of the fuse box(es) and may have a diagram of the relays.
2. Look in the fuse box under the hood: Carefully open the fuse box cover. Examine each relay, looking for markings that suggest it's for the fuel pump. Often there are diagrams inside the fuse box cover lid itself.
3. If you can't find it: Use a wiring diagram. You can find these online (search for "1993 Oldsmobile Cutlass Ciera wiring diagram"). These diagrams will show you the circuit path for the fuel pump and help you trace the relay's location.
Important Note: Before working with any automotive electrical components, disconnect the negative (-) terminal of your battery to prevent accidental shorts or damage. If you're not comfortable working with car electrical systems, it's best to take your vehicle to a qualified mechanic.
