Have Above Vehicle with a non start
On inspection observed little or no spark from 1 and 4 cylinders,
Garage has already tried coil and leads but fault still present
Noticed that the ign primary voltage and current are almost identical From 1 and 4 coil to 2 and 3 which are firing
Have read in the archives about Common ECU Faults for this with the SZR Engine but not for the X18XE Engine
Question is the current limiting cycle Shown in the links Below abnormal?
pin 1 and pin 2 of coil pack
Showing Red Voltage & Blue Current

Any help Greatly Appreciated
Terry
