Mi auto no enciende, no enciende el motor: Qué hago?

My Twingo won't start. When the engine won't start, it can be due to many reasons: a dead battery, one or more blown fuses, a faulty relay, a damaged fuel pump, a lack of fuel, loose spark plug wires or other wires, loose or dirty battery terminals, a faulty ignition coil or high-voltage module, a damaged starter motor, or a faulty crankshaft position sensor. In this video, I'll explain how to check each of these components so you can start your car quickly and easily.
