First make sure you have a fully charged battery. After that find out why the starter isn't turning over?

Is it cranking and not starting or just not cranking?

Not cranking - jump it, or needs a new battery or a charge if jumping won't cause it to crank.

Not starting - first, clean or replace your plugs, and crank the engine with the plugs out to get the oil out of your cylinders. Try that. If that doesn't work check for fuel and spark. Check ECM for codes as well.
