What are the reasons why the Malibu can power on but not start?

It may be due to insufficient battery voltage, but insufficient voltage does not mean there is no power. Below is relevant information about the battery: 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, depending largely on the vehicle's usage conditions. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. If using a multimeter for inspection, measure the battery voltage while cranking the engine. You can first use a high-frequency discharge tester or battery tester to measure it. Under a load current of no less than 110 amps, the minimum voltage should not be lower than 9.6 volts and should remain stable for 5 seconds. If the voltage is below 9.6 volts but can remain stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable within 5 seconds, dropping rapidly to 0 volts or close to 0 volts, it suggests the battery may be faulty and might need replacement.
I've driven a Malibu for ten years and encountered several instances where the car wouldn't start despite having power. The most common issue is insufficient battery charge – while the dashboard lights may illuminate, the starting current isn't strong enough to crank the engine. Another possibility is corroded or loose battery terminals causing poor contact; you can pop the hood to check if the connections are clean and tight. A faulty starter motor could also be the culprit, where you only hear a single click when turning the key without engine movement. Sometimes the anti-theft system acts up too, especially when the key fob battery is weak or the transponder chip is damaged, causing the system to lock out the starting function. My advice: first try jump-starting from another vehicle or cleaning the battery terminals. If that doesn't work, promptly visit a professional repair shop to inspect the ignition system and fuel pump – delaying could lead to more component damage. Develop regular battery maintenance habits like checking electrolyte levels and connections, and pay attention to dashboard warning lights to prevent issues proactively.
