What Are the Reasons for Having Power but Unable to Start the Engine?

The reasons for having power but unable to start the engine: 1. Insufficient fuel, it is recommended not to wait until the fuel tank is empty before refueling, as this can easily shorten the engine's service life; 2. Incorrect gear position may also cause the car to fail to start, P or N gear is the correct gear position for starting an automatic transmission car; 3. Circuit or electronic failure, such as blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plug; 4. Fuel system failure, possible issues include malfunctioning fuel pump, blocked fuel line, clogged fuel filter, carbon buildup on spark plugs, or damaged fuel injector.
I've encountered the issue of having power but the car won't start many times. The most common cause is a faulty starter motor—you can hear it clicking but the engine doesn't turn over, likely due to worn-out coils or gears inside. The fuel system can also be problematic, such as an empty fuel tank or a broken fuel pump, preventing fuel from reaching the engine and causing a no-start condition. Don’t overlook aging spark plugs or faulty ignition coils—without a proper spark, the engine won’t ignite. Also, remember the anti-theft system—a weak or poorly connected key fob battery can trigger a startup lock; simply replacing the battery might solve it. Starting won’t work if the gear isn’t in P (Park) or N (Neutral) either. Cold weather exacerbates these issues, so it’s wise to routinely check the battery voltage, refuel on time, and maintain your vehicle.
Friend, let me share some experience. This issue usually stems from the starting system or fuel supply: if the starter only makes noise but doesn't turn, it's often due to a stuck motor or gear; a faulty fuel pump or clogged filter will leave the engine without fuel to ignite; damp or damaged ignition coils or spark plugs can also prevent starting. Modern cars often have anti-theft systems that lock the vehicle, and if the key battery is dead, it won't start. Try turning the key on and off a few times, or gently tap near the starter to see if it responds. In winter, low temperatures can also cause starting delays, so warming up the car before trying again might help.
