Most car starting issues boil down to a dead battery, bad alternator, or faulty starter. First, listen for clicking sounds—rapid clicks often mean a weak battery or loose terminals. If you hear nothing, check battery voltage with a multimeter; it should be around 12.6V. Corroded or dirty connections can also block current. For a slow crank, the alternator might not be charging the battery. If the engine turns over but won’t start, look at fuel delivery or spark issues.
