You look in the repair manual.

A site like this on will give you the information needed, it offers a fairly good repair section.

Answer 3

A lot of libraries have repair manuals, but you can always go to an auto parts store and get one for about $15., it will have the correct firing order.

But before you go through any of that, look under the hood for service stickers, one of them will have tune-up specs including the firing order. The manufacturer always puts one in there when the car is built, but it could be missing or painted over.
