These safety features include:
* Inertia Switch (Crash Sensor): This is the closest thing to a traditional "safety switch." It's designed to cut power to the fuel pump in the event of a significant impact. However, its location varies by Escape trim level and it may be integrated into the vehicle's electrical system rather than a standalone switch. You'll likely need to consult a repair manual specific to your 2002 Escape model to find its location (if it's even a separate component).
* Fuel Pump Relay: This relay controls the power to the fuel pump. It's controlled by the PCM (Powertrain Control Module), which receives signals from various sensors. Finding the relay is your best bet if you're trying to diagnose a fuel pump problem. The relay location is usually in a fuse box (under the hood or inside the cabin), and a repair manual will show its exact location.
* PCM (Powertrain Control Module): The PCM monitors numerous inputs (like the crankshaft position sensor, etc.) and only allows the fuel pump to activate under normal operating conditions. This is the brains of the fuel pump safety system.
In short, there's no single, easily accessible "fuel pump safety switch." If you're having fuel pump issues, diagnosing the problem requires checking the fuel pump relay, fuses, and potentially consulting a repair manual or mechanic.
