Land Rover Range Rover Sport starts but cuts off after 2 seconds, new fuel pump installed on Land Rover Range Rover Sport

Some Land Rover Range Rover Sport owners report experiencing issues where the vehicle starts but cuts off after just 2 seconds. This frustrating problem can stem from various factors, necessitating accurate diagnosis for effective resolution. Some owners find that installing a new fuel pump can help, as a faulty pump is known to cause stalling issues. However, it is also crucial to check the fuel pump relay, as a malfunctioning relay can prevent the fuel pump from receiving power, leading to starting difficulties. In cases where the relay is functioning properly but the fuel pump still lacks power, some owners discover problems within the signal circuit, particularly in the central junction box and body control module. If the issue persists despite these measures, it is advisable for owners to consult a professional mechanic or Land Rover specialist for a thorough diagnosis and appropriate solutions.
