Fuel pump reset switch 1999 Silverado?

There's no fuel pump reset switch in a 1999 Chevrolet Silverado (or any modern vehicle, for that matter). Fuel pumps are typically controlled by the PCM (Powertrain Control Module) and don't have a manual reset mechanism.

If you're experiencing fuel pump problems, the issue is likely more complex and could include:

* Blown fuse: Check your vehicle's fuse box for a blown fuse related to the fuel pump.

* Fuel pump relay: A faulty relay can prevent the pump from operating. This needs to be checked and potentially replaced.

* Fuel pump itself: The pump might be failing due to wear and tear.

* Wiring issues: Damaged or corroded wiring can disrupt the power supply to the fuel pump.

* PCM issues: In rare cases, a malfunctioning PCM can prevent the fuel pump from activating.

Before attempting any repairs yourself (which can be dangerous if working with fuel systems), it's best to consult a qualified mechanic or use a reputable auto diagnostic tool to determine the precise cause of the problem. Simply trying to "reset" something that doesn't have a reset button won't fix underlying mechanical or electrical faults.
