Oldsmobile Alero engine won't turn over, only clicking noise despite new starter and battery on Oldsmobile Alero

Some Oldsmobile Alero owners report experiencing issues where the engine won't turn over, accompanied by a clicking noise, despite having installed a new starter and battery. These problems may stem from poor connections between the battery, starter, and related components, which can prevent the starter from receiving adequate power. Additionally, even though the starter is new, some owners find that it may still be faulty. A malfunctioning solenoid can also hinder the engine's ability to turn over, regardless of the starter's condition. In certain cases, issues with the Passlock system can lead to starting difficulties, requiring diagnosis and repair. Furthermore, insufficient fuel pressure, spark, or compression can contribute to these starting issues, necessitating a thorough check of these elements. For persistent problems, consulting a mechanic or automotive specialist for a detailed diagnosis is advisable.
