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.

One may educate the ignorance from the unknowing but stupid is forever. Boswell; ca: 1533

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.
