Instead, the fuel pump's electrical circuit often uses a larger fuse or a circuit breaker, which might be located:
* Under the hood fuse box: Look carefully, often the larger fuses are grouped separately. The fuse may be labeled, or you might have to consult your owner's manual for the correct fuse location and amperage. Your owner's manual is the best resource here.
* In the under-dash fuse panel: Less common for the primary fuel pump fuse, but possible. Again, check your owner's manual.
* In a separate fuse block: Some models might have a secondary fuse block located near the battery or elsewhere in the engine compartment.
To find the correct location, you absolutely MUST consult your owner's manual. This is the only reliable way to determine the fuse location and amperage for your specific 1993 Silverado. The manual will have a diagram of the fuse boxes and will list what each fuse protects. Trying to guess could lead to damage or injury.
