What could be the reason why the Malibu has power but won't start?

It may be due to insufficient battery voltage, as low voltage doesn't necessarily mean no power. Here's the relevant information: Battery: The battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. It refers specifically to lead-acid batteries, which are primarily made of lead and its oxides with sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, largely depending on the vehicle's usage. Battery Replacement: If the battery is dead, it's recommended to first measure the battery voltage. If using a multimeter, measure the battery voltage while cranking the engine. You can initially use a high-frequency discharge machine or battery tester for measurement. Under a load current of no less than 110 amps, the minimum voltage should not fall below 9.6 volts and must remain stable for 5 seconds. If the voltage is below 9.6 volts but remains stable for 5 seconds, it indicates over-discharge and requires timely recharging. If the voltage drops below 9.6 volts and fails to stabilize within 5 seconds, rapidly declining to 0 volts or close to it, this suggests a battery fault that may necessitate replacement.
Last time I drove a Malibu, I had a similar issue—lights and music worked but it wouldn’t start, which was really annoying. Possible causes include loose or corroded battery terminals, leading to insufficient power to crank the engine. Try tightening or cleaning the terminals. A faulty starter motor is also common; if you hear a clicking sound when turning the key but no response, the motor might be dead. If the fuel pump isn’t humming, it means fuel delivery is interrupted—could be a bad pump or a blown fuse. Sometimes the anti-theft system locks the engine, so confirm the key chip is recognized properly. For safety, avoid forcing it; towing it to a repair shop is wise. Long-term advice: regularly clean battery terminals and inspect the fuel system to avoid roadside embarrassments.
