Where is the fuel pump relay located on a 1990 Oldsmobile Cutlass Ciera?

The fuel pump relay location on a 1990 Oldsmobile Cutlass Ciera isn't standardized and depends on the specific trim level and options. It's *usually* found in one of these locations:

* Under the hood in the fuse box: This is the most common location. The fuse box is usually located near the battery, and the relay may be labeled, or you may need to consult your owner's manual or a wiring diagram to identify it.

* Inside the car, under the dashboard: Less common, but possible on some models. This would usually be in the fuse panel under the dash.

To find it, you should:

1. Consult your owner's manual: This is the best place to start. The manual will show you the location of all the fuses and relays, including the fuel pump relay.

2. Check the fuse box under the hood: Carefully examine all the relays. Some may be labeled, others might require cross-referencing with a diagram.

3. Look for a wiring diagram: A wiring diagram specific to your year, make, and model will show the location and circuit path for the fuel pump relay. These can be found online through various automotive repair sites or purchased at auto parts stores.

4. Use a multimeter: If you're comfortable with basic electrical work, a multimeter can help you identify the fuel pump relay by tracing the circuit. However, be cautious when working with electrical systems.

Without access to your specific vehicle's documentation, it's impossible to give a definitive location. Using the steps above, you should be able to find it.
