INFINITI G20 engine starts and dies after 30 seconds with check engine light on on INFINITI G20

Some INFINITI G20 owners report experiencing issues where the engine starts and then dies after about 30 seconds, accompanied by the check engine light illuminating. This situation often indicates a fault detected by the vehicle's computer that requires immediate attention. Common causes include fuel system issues, such as a clogged fuel filter or faulty fuel pump, which may prevent adequate fuel from reaching the engine. Additionally, sensor problems, particularly with the crankshaft or camshaft position sensors, can lead to the engine stalling if no signal is sent to the ECU. Owners may also encounter vacuum leaks that disrupt the air-fuel mixture, causing the engine to stall shortly after starting. In some cases, a faulty immobilizer may fail to recognize the car key, resulting in the engine shutting off. It is recommended for owners experiencing these symptoms to consult a qualified mechanic for diagnosis and prompt resolution to avoid further damage and ensure the vehicle's proper functioning.
