* Size: It's a relatively small rectangular component, typically about the size of a pack of chewing gum or slightly larger.
* Shape: Rectangular with square or slightly rounded corners.
* Terminals: It will have several terminals, usually 4 or 5, sticking out of the top or sides. These terminals will be connected to wires. They might be blade-type terminals (flat metal strips) or similar.
* Labeling/Markings: It may have some text or markings printed on it, possibly indicating its function ("FUEL PUMP," a part number, or similar). This is less reliable for identification than the location and circuit testing.
* Color: The plastic housing is likely black, but could be another dark color.
Instead of relying on visual identification alone, it's much safer to:
1. Consult your vehicle's wiring diagram: This will show you precisely where the fuel pump relay is located and which relay is the correct one. You can often find this diagram online or in a repair manual.
2. Use a multimeter: After locating potential relays, use a multimeter to test the continuity of each relay's contacts to confirm it's the fuel pump relay. This is the most reliable method.
3. Look for relay placement: The fuel pump relay is usually located in a fuse box or relay box, often under the hood but sometimes inside the vehicle's cabin. Consult your owner's manual or repair manual for the exact location.
Focusing on the location and using a multimeter will be far more reliable than trying to visually identify the relay based only on its appearance. Mistaking another relay could be disastrous.
