Ignition coil issue, fixed but now wont start

Hello..... please help if you can. I have a 56 plate nissan micra 1.2 activ for the wife. I was driving it the other day when all of a sudden smoke started coming out the bonnet and through the dash board vents and the smell of burning plastic. I let the car cool down and tried to start it but it wouldn't start but did try to turn over. After investigating an ignition cool had burnt out. These have now been changed along with the blown ecs fuse in the fuse box under the near side headlight. Thinking this would fix the problem the car won't now start.....on turning the key there is nothing.....please can anyone help????
