INFINITI G37 starting issue persists after new battery installation, radio and lights function but engine won't start on INFINITI G37

Some INFINITI G37 owners report experiencing starting issues even after installing a new battery, often due to several potential causes. Common problems include a dead battery, alternator issues, or a failed starter. In cases where the battery cranks the engine but the car does not start, the problem may stem from injectors, a dirty fuel filter, or electronic components like the ECU. Additionally, some owners find that their vehicle only starts with jumper cables, indicating a possible alternator malfunction. Other reported issues include dirty or loose battery terminals, water damage to the BCM from a sunroof leak, or parasitic draws from components such as the radio or amplifier draining power when the vehicle is off. For those experiencing these symptoms, seeking professional assistance is recommended to accurately diagnose and resolve the underlying issues.
