Here's why:
* Fuel Pump Relay: The 1994 Silverado uses a fuel pump relay to control the flow of electricity to the fuel pump. This relay is activated by the ignition system.
* Safety: Having a separate fuel switch would create a potential safety hazard as it could be easily left in the "on" position, leading to a fuel leak or fire.
* Electrical System: The fuel pump is designed to run only when the ignition is turned on or when the engine is running.
However, some aftermarket fuel switches are available for installation, but these are not standard equipment on the 1994 Silverado.
If you are experiencing issues with your fuel pump or suspect a problem with the fuel system, it's best to have a qualified mechanic diagnose and repair the problem.
