Instead, fuel delivery is controlled by a complex system involving:
* Inertia Switch: This is a safety device that shuts off the fuel pump in a collision. It's often located under the dash or in the engine compartment. This is the closest thing to a "cutoff" and might be what you're thinking of. To reset it, you'll usually find a red button that you press or a lever you need to move. The location varies by Ranger model year and trim level; check your owner's manual or online resources (like a Ranger forum) specific to your truck's year and model to locate it.
* Fuel Pump Relay: A faulty or tripped relay can prevent the fuel pump from operating. This is not a switch you deliberately turn on or off; it's an electrical component. If you suspect a relay problem, you'll need to locate the fuel pump relay (in the underhood fuse box, typically) and either replace it or check the connections.
* Fuel Pump: The fuel pump itself can fail. If the pump is faulty, you'll need a replacement.
* Other Electrical Issues: A problem with the wiring harness, the PCM (Powertrain Control Module), or other sensors could also prevent fuel delivery. Diagnosing these requires specialized tools and knowledge.
Therefore, to troubleshoot your fuel problem:
1. Check the inertia switch first. This is the easiest and most likely candidate if the truck suddenly stopped running.
2. Check the fuel pump relay. Make sure it's properly seated and not damaged.
3. Listen for the fuel pump: When you turn the ignition key to the "on" position (but don't start the engine), you should hear the fuel pump briefly prime. If you don't hear it, the pump, relay, or wiring might be the problem.
4. If none of the above work: You'll likely need to take your Ranger to a mechanic for proper diagnosis. The issue could be far more complex than a simple switch reset.
Without more information on the symptoms (e.g., did the truck suddenly die, is there a specific event that preceded the problem?), it's impossible to provide more specific advice. Consult your owner's manual or seek assistance from a qualified mechanic.
