To find it, you'll need to:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram of the fuse and relay box locations.
2. Check under the hood: The relay is typically located in the under-hood fuse box or a separate relay center. The fuse box is usually near the battery.
3. Check under the dash: In some models, relays might be located in a fuse box under the dashboard.
4. Look for diagrams online: Search for "1993 Chevy van [your specific model] fuse box diagram" This will give you a visual aid to locate the relay. Be sure to double-check the year and model to ensure accuracy. Sites like autozone.com often have these diagrams.
5. Check the relay itself: The relay itself might be labeled "fuel pump" or have a designation that corresponds to the fuel pump circuit in your vehicle's wiring diagram.
Important Note: Before working on any electrical components, disconnect the negative battery terminal to avoid accidental short circuits.
Without knowing the exact model of your 1993 Chevy van, I cannot give a more precise location. The steps above are your best approach to finding it.
