What is the reason why the Cruze won't start despite having fuel and electricity?

This situation may be caused by a malfunction in the ignition system or the intake system. When this occurs, it is necessary to inspect the ignition and intake systems. A car engine requires air for combustion, as well as a functioning ignition system. Without air, gasoline cannot burn. Below are the solutions for the possible issues: 1. Ignition System: The ignition system is specific to gasoline engines, with key components including the ignition coil and spark plugs. 2. Spark Plugs: Spark plugs are wear-and-tear parts that require regular replacement. Over time, the electrode gap in the spark plugs may widen. If the electrode gap becomes too large, it can weaken the spark plug's ignition energy, leading to incomplete combustion of the air-fuel mixture in the engine. Prolonged failure to replace spark plugs can result in the spark plugs being unable to generate a spark. 3. Ignition Coil: The ignition coil connects to the spark plugs and is responsible for increasing voltage. Only with sufficiently high voltage can the spark plugs ignite properly. Although the ignition coil is not a part that requires regular replacement, it is prone to damage due to prolonged exposure to high temperatures. If the ignition coil is damaged, the spark plugs will also fail to generate a spark. A damaged ignition coil must be replaced immediately.
It's quite common for a car to have fuel and battery power but still fail to start, especially with older vehicles. I suspect the starter might be faulty—like when the motor doesn't respond or just hums during ignition. Even though you mentioned having power, the battery could be aged, causing voltage to drop during ignition and preventing the starter from working. Another possibility is an issue with the ignition system, such as excessive carbon buildup on the spark plugs, which can hinder sparking. The anti-theft system might also malfunction; if the key chip is damaged, the car's computer may mistakenly assume theft and block startup. My advice: first check if the battery terminals are loose and tighten them. If that doesn’t help, inspect the starter-related fuses in the fuse box for any signs of melting. Avoid forcing the ignition to prevent circuit damage, and take the car to a proper repair shop as soon as possible—DIY attempts could waste time and money.
I often hear friends complain about this situation, especially with cars like the Chevrolet Cruze. Although both fuel and electricity are confirmed to be available, the key lies in the details: the battery appears fully charged, but lacks power during startup, possibly due to a worn starter or a minor issue causing it to jam; the ignition coil may be old, and the spark plugs aren't firing properly; sometimes, the anti-theft system is overly sensitive, locking the engine due to key malfunctions or signal interference. I once encountered a case where a relay overheated and short-circuited, interrupting the starting circuit. Don't panic—start with simple checks: try using a different key or the spare key to see if it's an anti-theft issue; then inspect whether the starter relay is functioning properly. Safety first—if the car breaks down on the road, engage the handbrake, turn on the hazard lights, and call for roadside assistance immediately to avoid accidents.
