The car mentioned in the title won't start, no error code. What we've tried: new spark plugs, transformer, ignition cables, fuel pressure OK, battery OK, immobilizer OK, compression OK. Visually checked (in disassembled state), the injectors are feeding and there is spark at all spark plugs. The crankshaft sensor has also been replaced. After standing for a long time, it gives some good noise, but does not start at all. We are at a loss.

How long is a long time ?!!

Have you removed the old fuel and added fresh fuel?

This car is in a daily usage, fresh fuel. Long time means, some hour of stoppage between start attempts. Here is two video about spark and fuel activity.

Could it have been mis-fuelled with diesel?

No, it is 100 octane premium fuel.

I know you've mention compression is ok but is the camshaft turning when trying to start - aka cambelt issue?

I assume the two plugs sparking at same time is a wasted spark system I may be wrong but firing order is I think 1,3,4,2 as in your vid of the injectors fuel pattern but it doesnt seem to match sparking pattern. Seems to spark 5 times on 2,3 and then 5 times on 1,4

My brain was telling me something could be amiss when I watched the vid, but I couldn't work out what it was. Hopefully you've caught it.

Im used to diesels and old old pertrol/lpg with distributors etc. The double spark confused me first but found out about wasted spark systems but to me something doesnt look right. As said may be wrong
