If your fuel pump isn't working, the problem is more likely one of these:
* Blown fuse: Check your owner's manual for the fuel pump fuse location and replace it if blown.
* Faulty fuel pump relay: This is a common culprit. You'll need to locate the relay (usually in the underhood fuse box) and either replace it or try swapping it with a similar relay to see if that resolves the issue.
* Faulty fuel pump: The pump itself may have failed. This requires replacement.
* Inert Fuel Pump Inertia Switch: While not a "shut-off switch" in the traditional sense, the inertia switch (a safety device that cuts power to the fuel pump in a collision) is a possibility. Locate this switch (usually under the dash or in the engine compartment, check your owner's manual) and see if it's tripped. Often, there is a button you can press to reset it. The location may vary by trim level.
* Problems within the PCM: This is less likely, but a malfunctioning PCM could prevent the fuel pump from activating. Diagnosis would require a scan tool.
* Low fuel: Ensure you have enough fuel in the tank. The low fuel level might trigger a safety shutdown.
* Wiring issues: Damaged wiring between the PCM, relay, and fuel pump can interrupt power. This requires thorough inspection.
Before attempting any repairs: Disconnect the negative battery terminal to avoid electrical shorts.
To find the location of the inertia switch and fuses/relays: Consult your owner's manual. It's the best resource for specific locations in your particular 1995 Ford Ranger model. You can often find a free PDF online if you don't have a physical copy.
If you're not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic for diagnosis and repair. Attempting repairs without the proper knowledge can lead to further damage or injury.
