If you're having fuel delivery problems, the issue isn't likely a switch but rather:
* The fuel pump itself: This is the most common culprit.
* The fuel pump relay: This relay acts as an intermediary between the PCM and the pump.
* The PCM: A faulty PCM could prevent the pump from engaging.
* Wiring issues: Problems in the wiring harness leading to the pump can also cause failure.
* Inertial switch: Some Rangers have an inertial switch (a safety device that cuts power to the fuel pump in a collision) that may have tripped. This is usually located under the dash or in the engine compartment.
To diagnose fuel delivery problems, you'll need to consult a repair manual specific to your 2001 Ford Ranger XLT or take it to a mechanic. Trying to troubleshoot the fuel pump system without proper knowledge can be dangerous due to the flammable nature of fuel.
