Volvo C70 engine starts briefly then fails to run, unable to fire after multiple attempts on Volvo C70

Some Volvo C70 owners report experiencing engine starting issues, where the engine starts briefly but then fails to run despite multiple attempts. This problem may stem from battery or starter issues, indicating that the battery might not be providing sufficient power to start the engine. Additionally, intermittent starting problems are noted, such as a lack of initial rev when starting a warm engine or no fast idle on a cold engine, which can contribute to the failure to run properly. Some owners have found that a faulty immobilizer antenna ring can cause starting difficulties, and replacing this part may resolve the issue. Furthermore, the presence of a high-speed fan running when starting a hot engine could signal an underlying problem that requires dealer inspection. Lastly, engine modifications, such as remapping or chipping, may affect performance and lead to starting issues, making it crucial for owners to verify compatibility. It is advisable for affected owners to consult a qualified mechanic or a Volvo dealership for proper diagnosis and resolution of these issues.
