Volvo XC70 engine starts but shuts off immediately after ignition on Volvo XC70

Some Volvo XC70 owners report experiencing issues where the engine starts but shuts off immediately after ignition, which may be attributed to several factors. These include the immobilizer system being triggered, leading to an immediate shutdown of the engine. Additionally, fuel delivery issues, such as a faulty fuel pump or a blocked fuel filter, can result in a lack of fuel reaching the engine. Problems with the ignition system, like a faulty ignition switch or ignition lock cylinder, may also cause the engine to die right after starting. Furthermore, some owners report difficulties with the control of the fuel injection system, which can lead to the engine shutting off. Lastly, if the vehicle enters a reduced performance mode with a warning message like "Engine system service required," this could indicate underlying issues that need attention. It is advisable for owners experiencing these problems to consult a qualified mechanic or Volvo specialist for proper diagnosis and resolution.
