Why is there no response when starting the car and no engine sound?
4 Answers
No response when starting the car and no engine sound may be due to a dead battery. Here is an introduction about the engine: 1. Introduction: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816, which was later improved by Watt into a steam engine. 2. Application: The engine can be used as a power generation device or refer to the entire machine including the power device (e.g., gasoline engine, aircraft engine). 3. Categories: Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, etc.
Last time my car had the same issue, there was absolutely no response when starting, as if turning the key was just for show. Common causes are mainly a dead or depleted battery, especially if the lights won't even turn on, which pretty much confirms it. It could also be a faulty starter motor or ignition system problem, like worn switch contacts. I remember that winter when my car sat for a week and then wouldn't start silently—turned out the battery terminals were loose, and tightening them fixed it. If the dashboard shows no lights, try listening for a faint click when turning the key; if there is one, the starter might be stuck. For safety, avoid cranking too many times in a row to prevent further draining the battery. It's best to check with a voltmeter or just take it to a mechanic to avoid delays and trouble. For prevention, regularly check the battery's health.
After years of car enthusiasm, I've summarized the reasons for no response when starting the engine. First, it could be insufficient battery power failing to crank the engine. Secondly, the starter motor might be completely dead. Or there could be electrical issues like a blown fuse or faulty relay. For example, if the headlights turn on but the engine makes no sound during startup, it points to a starting system malfunction. You can pop the hood to check if the battery terminals are corroded or loose—clean them thoroughly if dirty and try again. The relay box is usually tucked in a corner of the engine bay. For daily drivers in cold climates, pay extra attention to maintenance as batteries age faster and are prone to issues. Using a multimeter to check battery voltage is highly practical—anything below 12 volts is risky. Don’t overlook these details to avoid delaying repairs.
I've encountered this issue before. The main causes include a dead battery unable to supply power, a faulty starter motor that won't turn, a damaged ignition switch, or a blown fuse. First, check if there are any dashboard lights - if they're completely off, it's likely a battery problem. Try turning on the headlights or honking the horn to check the power status. If they work but there's no sound when starting, inspect the motor circuit. Reminder: Always ensure the car is in neutral before starting to prevent accidental movement. Seeking professional repair is the safest approach - never force-start the vehicle as it may damage the electrical system. Regular maintenance can help prevent such issues from occurring.
