Here are some possible scenarios and troubleshooting steps:
* Fuel Pump Failure: The fuel pump might have failed. This requires mechanical work (replacing the pump) and is not a simple reset.
* Fuel Filter Clog: A clogged fuel filter restricts fuel flow. Replacing the fuel filter is relatively straightforward but requires some mechanical skill.
* Fuel Injector Problems: A faulty fuel injector can prevent fuel from reaching the engine. Diagnosis and repair require specialized tools or a mechanic.
* Ignition System Issues: A problem with the ignition system (distributor, coil, spark plugs, etc.) can prevent the engine from starting, even if there's fuel.
* Fuel Pump Relay: While less common, a faulty relay could prevent the fuel pump from activating. You can try replacing this relatively inexpensive part.
* Dead Battery or Electrical Problems: A dead battery or other electrical problems can prevent the fuel pump from functioning, even if the pump itself is fine.
Instead of looking for a reset, focus on diagnosing the *cause* of the fuel problem:
1. Check the obvious: Do you have a full tank of gas?
2. Listen for the fuel pump: Turn the ignition key to the "on" position (don't crank the engine). You should hear a brief whirring sound from the fuel pump in the fuel tank. If you don't, the pump or its relay might be faulty.
3. Check fuses and relays: Consult your owner's manual to locate and inspect the fuses and relays related to the fuel system.
4. Have it checked by a mechanic: If you're not comfortable performing these checks yourself, take your Mustang to a qualified mechanic for diagnosis and repair.
In short, there's no reset button; you need to find and fix the underlying issue causing your fuel-related problem.
