When a jet is pushed back from a gate does it need to face into the wind in order or the engine to start up. Or does this matter at all?

I thought I was doing good trying to avoid those airport hotels... and look at me now.

It used to. On the original 747 for example, there was a tailwind limitation for start-up, about 15 knots I believe.

A pilot is "encouraged" to not have a direct breeze up the tailpipe on starting. It can make for a very pretty (and sometimes exciting) display if there's a weak igniter. Each company has their own policies based on the appropriate manufacturer's operating and maintenance manuals.

At my company (regional Saab 340 operator), aircraft are (when possible) positioned into the expected wind to avoid a hot-start or ingestion of exhaust gases into the cabin -- this is especially noticeable on the first flight of the day, as the oil that seeped overnight burns off.
