Hello, Eddie here and I will do my best to help. Have you confirmed that you have no spark to the spark plugs when cranking?

I connected a bulp to the cables feeding the coil, the bulb lits for one sek. and then no light. when I turn my key it lithts up one sek. and I continue trying to crank engine

You'll need to pull a spark plug wire off, directly off a spark plug, and with a spark tester that plugs into the spark plug wire crank it over and see if your getting any spark while cranking. If not, and you already tried a crank sensor. I believe your power stage has likely failed, over by the battery on the firewall. Those ignition boxes under the dash hardly ever fail. But I have had to put a few one, it's just not likely.
