I would start with checking the igition coil pack for power. If there is power to circuit you may want to see if you could swap one with a known good coil pack. Any codes set?

Any diagnostic codes. Check engine light? You may have to have it scanned at a shop

When I turn the key on on, engine light is on.
But when starts the engine, it past 2-3 seconds and engine light go to off. But he wont starts. That was before.
But now its on when I turn the key!

Yeah your going to have to get the vehicle scanned to check what codes are stored and also if your getting a spark signal from coil and crank sensor.

How to scan my car?
I didnt tell you.
When my battery was dead, I jump start my car.
When I conect the cables, in that moment, something is burn, and smoke has its shown, its only smoke come on, not a fire.
I dont know why its smoke come on, it was good conected (+/+ -/-).
When that happend I cant start my car!
And everthing working ok now, but no sparks to the plug.
I am from serbia, sorry if my english is bad. : D

Your english is good no worries. It is possiable that a voltage spike from jump starting the vehicle may have damaged a module. You found have to bring the vehicle to a repair facility that can read any codes set, and check powertrain control data.

I have one more question.
Did you mean ignition module,
which activates ignition coil?
Maybe that can burn?
