Chevrolet Cobalt won't start, only clicks despite key battery and starter replacement on Chevrolet Cobalt

Problem overview

Some Chevrolet Cobalt owners report experiencing starting issues characterized by a clicking sound, even after replacing the key battery and starter. These problems may stem from a weak battery, which can lead to insufficient power for cranking the engine. Additionally, corrosion on battery terminals can disrupt electrical connections, while poor starter electrical connections may also result in clicking noises without engine engagement. A bad ground connection is another potential culprit that can hinder the starter motor's operation. In some cases, a faulty starter motor itself could be the reason for the clicking sound and failure to start. To troubleshoot these issues, owners are advised to check battery cables for damage, scan for trouble codes, ensure all grounds and connections are secure, and consult a professional for further inspection of ignition switches, solenoids, and relays. Following these steps may help in diagnosing and resolving the starting difficulties in the Chevrolet Cobalt.
