How to troubleshoot a faulty fuel pump in an Audi A4?

I noticed my Audi A4 is having trouble starting and the engine is misfiring. I suspect it could be a problem with the fuel pump. How can I accurately diagnose and fix this issue on my own?

The first step would be to check the fuel pump relay and fuse. These are often the culprits for a faulty fuel pump. If they are both functioning properly, then it is likely time to replace the fuel pump itself.
