* No start: The car won't crank or turn over.
* Weak start: The car cranks slowly and struggles to start.
* Stalling: The engine dies while driving or idling.
* Surging: The engine power fluctuates erratically.
If you're experiencing any of these, you should have a mechanic diagnose the problem. It's unlikely a simple reset will fix a malfunctioning fuel pump; the pump itself or related components might need replacement or repair.
