It's not starting and I put it on the code thing and these are the codes that came up on it: p0171, p0441, p0101, p2279. What do they mean? The other day my car smelled really rich the gas you could smell a lot.

Hi,

These codes indicate a vacuum leak as the most likely cause. Is there any history to this or did it just start doing this one day?

Here are some guides that will walk through the basics of this issue:

Let's start with checking for vacuum leaks and then go from there. If it is bad enough it will not allow the engine to run because there is just to much unmetered air going into the engine.
