Volvo C70 engine dies after running, multiple components replaced including shutdown solenoid and ignition relay on Volvo C70

Some Volvo C70 owners report experiencing engine stalling issues even after replacing parts like the shutdown solenoid and ignition relay. These problems can stem from a failing signal to the fuel pressure relay, which affects consistent fuel delivery, leading to the engine starting and then dying. Additionally, contamination in the fuel injection system is another common culprit that can cause stalling, emphasizing the need for a clean and properly functioning fuel system. A malfunctioning Mass Air Flow (MAF) sensor may also contribute to the engine shutting down after starting, and checking or replacing this sensor could be necessary. Furthermore, immobilizer issues can lead to inconsistent fuel delivery, resulting in similar stalling problems. To effectively diagnose and address these issues, Volvo C70 owners should consider these potential causes and prioritize regular maintenance and thorough troubleshooting.
