If you're having fuel pump problems, the issue isn't likely to be solved by a nonexistent switch. Instead, you should consider these possibilities:
* Low fuel: Make sure the gas tank isn't nearly empty.
* Fuel pump relay: This component might have failed. A mechanic or online resources can help you locate and test the relay.
* Fuel pump itself: The pump might be failing, requiring replacement.
* Faulty fuel pump fuse: Check your fuse box for a blown fuse related to the fuel pump.
* ECM issue: A problem with the engine control module could prevent the pump from activating. This is less common but possible.
Instead of looking for a switch, you should take your 1995 Chevy to a mechanic or diagnose the problem using a diagnostic tool or repair manual.
