The fuel pump just went on my Vibe (at least that's what I'm told is the reason it's not starting.

1. How hard is this job to do? He's an apprentice tech, so he knows a bit. Is it difficult to get at the fuel pump and replace it? He can work on it at work, so he'll have a lift and all his tools and whatnot.
2. Is it the same fuel pump as the Toyota Matrix of the same year? I called a local auto parts store, and for some reason the fuel pump for the Vibe was $4-600 (and was a whole assembly, not sure what that entails), and for the Matrix, it was just the pump and cost like $100. Any ideas what that's about?
Thanks in advance for any help
