Where is the fule relay switch located at on a 1988 Chevy silverado suburban?

The fuel pump relay location on a 1988 Chevy Silverado Suburban varies slightly depending on the specific trim level and options. It's *not* typically a switch you manually flip. It's a relay that's activated by the computer.

The most common locations are:

* Under the hood in the fuse box: This is the most likely place. Open the hood and locate the fuse box (often near the battery). The relay itself might be labeled, or you might need to consult your owner's manual or a wiring diagram to identify it. Look for a relay with markings related to fuel injection or the fuel pump.

* Under the dash: Less common, but possible on some models. This would be within the fuse panel or a separate relay box under the dash.

To find it definitively:

1. Consult your owner's manual: This is your best bet. It should have a diagram of the fuse box and relay locations.

2. Use a wiring diagram: A wiring diagram specific to your 1988 Silverado Suburban will show the location and the circuit for the fuel pump relay. You can usually find these online through automotive parts websites or repair manuals.

3. Check online forums: Search online forums for "1988 Chevy Silverado Suburban fuel pump relay location." Owners of similar vehicles might have posted pictures or descriptions.

Important Note: Before working with any electrical components, disconnect the negative terminal of your battery to prevent accidental shorts or shocks.
