I have a bit of a problem. No spark! I have a 96´Baleno 1.3l engined. Chek engine is flashing. I made some self diagnostics and it flashes me a code 81

I also checked all the other ignition components all seems to be fine(distributor etc...) I tried to replace some parts but still nothing! I check´d all connections and wirers which are connected to the ignition system. This fault came over night! Yesterday it was driving ok! Today check engine

Where can i find wirering diagrams?(i searched but nothing...)
