Chevrolet Impala ignition issue with no response despite fully charged battery on Chevrolet Impala

Some Chevrolet Impala owners report experiencing ignition issues, where the vehicle shows no response despite having a fully charged battery. This problem may be attributed to a failing ignition switch, which can hinder the vehicle's ability to start. Additionally, some owners find that a faulty starter motor or its connections can prevent the engine from cranking. Even with a charged battery, issues such as a defective battery or problematic battery cables may still arise. The presence of a malfunctioning ignition cylinder with a passlock chip can also contribute to the no-start condition. Furthermore, underlying electrical problems, including issues with the powertrain control module (PCM) or electrical shorts caused by components like the EBCM or ABS, may be at play. To address these concerns, it is recommended that owners check battery connections, inspect the starter motor, test the ignition switch, ensure proper fuel pump operation, and examine spark plugs for wear. If the issue persists, seeking assistance from a qualified mechanic or automotive technician is advisable for effective resolution.
