Hi Guys sorry if this has been posted before but i have a problem with my S4 It is turning over fine but there is no spark, hence not firing. I had the breakdown people out to look at it as i was stranded in some god forsaken 3 thumb town. They said it was the ignition module (ECC) or crank centre sensor. I looked in my manual at the fault diagnostics and cant find anything remotely similar. Any ideas?
