However, it's most commonly found in one of these locations:
* Under the hood in the fuse box: This is the most frequent location. The fuse box is usually located near the battery. Check the fuse box diagram on the inside of the cover to locate the fuel pump relay. It might be labeled "Fuel Pump," "EFI," or something similar.
* Under the dash: Less common, but possible on some models. Check the fuse block or relay panels under the dashboard. Again, consult the fuse box diagram.
* Behind the glove compartment: Another less likely, but potential location.
To find it definitively:
1. Consult your owner's manual: This is the best place to start. The manual will have a diagram of the fuse and relay boxes.
2. Check online forums: Search for "1990 Chevy [Your Truck Model] fuel pump relay location" on forums like ChevyTalk or similar. Owners of your specific truck model are likely to have discussed this.
3. Use a wiring diagram: A wiring diagram for your specific truck year and model will show the location and circuit for the fuel pump relay. You can find these diagrams online or at auto parts stores.
Without knowing the exact model and body style of your 1990 Chevy truck, providing a more precise location is impossible.
