I guess your engine has 2 coil packs,
serve 2 x cylinders each,
quite common for these to fail,
TRY THIS=
STOPcar,
unplug 1 x coil packs lead, start car,
it may be the same , or NOT START / RUN
TURN OFF car ignition,
reconnect this coilpack,
unplug other coil pack ,
try again to start the car,
if 1 pack makes ZERO difference to running of engine , replace that coilpack,
good luck,
