Electric Fuel pump problem n engine dead

Hello, my name is Zam and I'm from Malaysia. I recently experienced an issue while riding my GSA R1200 (2018), where the engine suddenly stopped working and displayed a warning message. After attempting to restart it, the bike wouldn't start up again. The mechanics suspect a fuel pump failure, but I'm open to other ideas as well. I'm in need of help because the cost to replace the fuel pump is quite high. Any suggestions would be greatly appreciated. Thank you!
