If you're experiencing fuel delivery problems (e.g., the engine won't start, or is running poorly), the problem is likely something more serious than needing a simple reset. Possible causes include:
* Bad fuel pump: This is the most common culprit.
* Fuel pump relay: This is a small electrical switch that controls the pump.
* Clogged fuel filter: This restricts fuel flow.
* Low fuel: Sounds obvious, but worth checking!
* Faulty fuel pressure regulator: This regulates the pressure in the fuel system.
* Problems in the fuel pump wiring: A short or broken wire could prevent power from reaching the pump.
* Inertial fuel pump cutoff switch (if equipped): Some vehicles have a safety switch that cuts power to the fuel pump in a collision. This should be checked if you have been in an accident.
You'll need to have a mechanic or use a diagnostic tool to pinpoint the problem. Attempting to bypass or "reset" the fuel system without understanding the issue could be dangerous.
