Where is the fuel pump relay located on a 1992 Oldsmobile Cutlass Cierra?

The fuel pump relay location on a 1992 Oldsmobile Cutlass Ciera isn't standardized across all models and trim levels. It could be in the under-hood fuse box (often labeled "Power Distribution Center" or PDC), or possibly in a separate smaller fuse box, often located inside the passenger compartment (sometimes under the dash).

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The manual will have a diagram showing the location of all relays and fuses.

2. Check the under-hood fuse box: Look for a diagram on the inside of the fuse box lid. This diagram will usually identify relays by their function (e.g., fuel pump, ignition).

3. Check for a separate fuse box inside the car: Some models had additional fuse boxes. Look under the dash, often near the steering column or on the driver's side.

4. Look for a relay that is labeled: Even without a diagram, look for a relay that might be labeled "Fuel Pump" or have a symbol that suggests fuel.

5. Use a wiring diagram: If you can't find it visually, a wiring diagram specific to your 1992 Oldsmobile Cutlass Ciera will show the relay's location. These can be found online (through sites like Haynes or Chilton) or at auto parts stores.

Important Note: Before working on any electrical components, disconnect the negative terminal of your battery to prevent accidental short circuits. Be careful when removing and replacing relays – they are delicate.
