What are the reasons for a car not starting when it has electricity?

The reasons for a car not starting when it has electricity include: 1. Issues in the circuit or ignition system; 2. Failure to replace spark plugs for a long time, leading to increased electrode gap and carbon buildup on the electrodes; 3. The steering wheel is in a locked state; 4. Insufficient fuel in the car; 5. The car battery voltage is too low to power the starter. The solutions for a car not starting when it has electricity are: 1. Clean the throttle valve, intake tract carbon deposits, fuel injectors, etc.; 2. Replace the spark plugs; 3. Check the fuel pressure regulator, fuel pump, fuel filter, and pipelines.
I once encountered a situation where the car had power but wouldn't start. It happened on a winter morning—the lights were on, the radio worked, but the engine just wouldn't crank. The most likely cause was a faulty starter, either due to a stuck starter gear or loose electrical connections. Another common issue is ignition system failure, such as worn spark plugs or a bad ignition coil, leading to unsuccessful ignition. Fuel problems are also frequent culprits—if the tank is nearly empty or the fuel pump isn't working, fuel can't reach the engine, preventing startup. In cold weather, diesel vehicles are prone to fuel gelling, but gasoline cars can face similar issues. I remember that time, after towing it to the repair shop, they diagnosed a faulty crankshaft position sensor. This tiny component, when defective, can confuse the engine control module. Preventive measures include regular maintenance, like checking the starter and spark plugs, to avoid roadside breakdowns. In such cases, stay calm first and try listening to the startup sounds to identify the problem source.
