They would run if one plug was firing correctly but the second isn’t ,,,, Mine had two plugs wires swapped around once by a mechanic .... 4 cylinders were fine with both plugs in each cylinder firing at the same time .... 2 cylinders had one plug each firing at the right time, but both had their second plug firing at a different time in the stroke. You can see how This happens if you look at the instructions I posted earlier for the firing order..
Eg two coil packs fire on one cylinder so coil pack A1 fires a plug in cylinder 1 and in cylinder 4 :
Coil pack A1 ... fires cylinder 1 top plug
Coil pack A2.... fires plug cylinder 1 lower plug
Coil pack A1 ... fires cylinder 4 top plug
Coil pack B2 .... fires plug cylinder 4 lower plug
Notice it also states do not wire one coil pack to both plugs on cylinder 1 as it would place the load of 2 plugs under compression on one coil pack and a severe performance problem would result.
Not trying to push this but think our descriptions are crossed wires slightly so kind of hoping you see where I’m coming from. We are currently in lockdown in the uk so have nothing better to do than think about tech problems like this , wether we’re right or wrong is another matter...
