If you're having fuel-related problems with your Ford Explorer, it's *not* a matter of resetting a switch. Here are some possibilities and how to troubleshoot:
* No fuel pump prime: If you turn the ignition key to the "on" position (not starting) and don't hear the fuel pump whir for a second or two, there could be several issues. This doesn't necessarily mean a switch is bad; it could be:
* Low fuel: Check your fuel gauge.
* Blown fuse: Check the owner's manual to locate the fuel pump fuse and inspect it.
* Fuel pump relay: This is an electronic switch that the PCM uses to control the fuel pump. A faulty relay could be the culprit. Your owner's manual should help identify this.
* Faulty fuel pump: The pump itself may have failed.
* Wiring issues: A damaged wire between the PCM, relay, and fuel pump could interrupt power. This requires professional diagnosis.
* PCM problem: Rarely, the PCM itself could be faulty and needs professional attention.
* Intermittent fuel pump operation: This points to wiring, the relay, or possibly the fuel pump itself.
* Fuel pump runs constantly: This is a serious issue usually indicating a problem with the PCM or its wiring. The vehicle needs professional diagnosis and repair.
What to Do:
1. Check the obvious: Start with the simplest things – is the fuel tank low? Is the fuse blown?
2. Consult your owner's manual: It will show you the location of fuses and relays.
3. Get professional help: If you're not comfortable working on your vehicle's electrical system, take it to a qualified mechanic or auto electrician. They have the tools and expertise to diagnose the problem accurately and safely. Trying to fix electrical issues without proper knowledge can be dangerous and may cause further damage.
Don't attempt to bypass or "reset" anything related to the fuel system without understanding the potential consequences. Improperly working with the fuel system can be dangerous and lead to fire or explosion.
