I have an x308 and I think there's a short somewhere in relation to the fuel pump. Every time I replace the fuel pump fuse, after trying to start the engine, the fuse just blows again. Instead of trying to guesstimate where the short could be occurring, does anyone know where I can start to look for the cause of it?

 

I forgot the mention, before this whole fuel pump fuse situation, there were these trouble codes - P0305, P1316, and P1643. When the car was running, there would be a rough idle.

Would any of these be related?
