The 1995 Ford Ranger doesn't have a fuel pump switch in the way some older vehicles do. The fuel pump is controlled by the engine computer (Powertrain Control Module or PCM) and is activated when the ignition key is turned to the "on" position (or by the starter when cranking). There's no separate on/off switch accessible to the driver.
If you're having fuel pump issues, it's likely a problem with the PCM, the fuel pump relay, the fuel pump itself, or the wiring to those components. You'll need to diagnose the problem using a multimeter or a scan tool to determine the source of the failure.
