Hello guys!
What could be the problem? Why could only one ignition coil give out spark, the other three are not giving spark? Could all of the three ignition coils fail at a time? Maybe it is the ECM problem? What other components to test out? Need ideas. Spark plugs changed to new, same problem..
As you crank the engine it is trying to start but very hardly, as only one coil is working.

Solved the problem...
The cause was the "midi fuses" behind the normal fuses. The midi fuses are deeper in the glove box compartment, you have to remove the whole glove box, to reach those. Oxidation on the midi fuses caused bad contact, cleaned lubed with spec. Electronics lube to prevent oxidation. Hope this tip helps someone out there some time!
