* Under the hood in the fuse/relay box: This is the most common location. The fuse box is typically located near the battery or on the driver's side fender well. Check the diagram on the inside of the fuse box cover for the fuel pump relay. The diagram should identify the relay and its function.
* Under the dash: Less common, but possible. Again, check your owner's manual or a wiring diagram.
* In the Body Control Module (BCM): In some cases, the fuel pump control might be integrated into the BCM, which may or may not have replaceable relays.
To find it:
1. Consult your owner's manual: This is the best first step. The manual will have a diagram showing the location of all fuses and relays.
2. Check the fuse box under the hood: Carefully examine the diagram inside the cover. Look for a relay labeled "fuel pump," "EFI," or something similar. If unsure, compare the relay's physical size and shape to the diagram.
3. Use a wiring diagram: You can find wiring diagrams online (various automotive repair sites sell them) or at a local auto parts store. A diagram will pinpoint the exact location and show the wiring.
4. Search online forums: Searching online forums specific to 1995 Chevy G20 vans might provide additional clues from other owners who have located the relay. Be sure to include your engine size in your search.
Important Note: Before working on any electrical components, disconnect the negative terminal of your battery to avoid any potential short circuits.
