Where is fuel pump relay in 1996 cadillac sedan deville?

The fuel pump relay location in a 1996 Cadillac Sedan DeVille is in the underhood fuse block/relay center. However, there isn't a single, universally labeled "fuel pump relay." The relay may be integrated into the Body Control Module (BCM) or it might be a standard relay within the fuse box, but it's not always clearly identified as such.

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The diagram should show the location of the fuse box and may identify the fuel pump relay (though it might be labeled something less specific like "Engine Control Relay" or similar).

2. Use a wiring diagram: A wiring diagram for your specific year and model is crucial. You can find these online (often for a fee) through repair manual providers or automotive parts websites. The diagram will show the circuit for the fuel pump and identify the relevant relay.

3. Examine the fuse box: Once you locate the underhood fuse box, carefully examine the relays. Many are interchangeable in appearance, so you *cannot* simply swap relays based on looks alone. Again, the wiring diagram is essential here. You might try looking for relays near those that control engine components.

Warning: Incorrectly replacing relays or fuses can cause further damage. If you are not comfortable working with automotive electrical systems, take your vehicle to a qualified mechanic.
