Have wrote loads on the "K and KE ".....system on this site....do remember continual cranking of the starter, and the engine not starting .....will cause the "5th injector" "Timer" to cut in....and shut down any neat Fuel from getting in the manifold.... will take 15mins to reset.. this is the safety feature to stop an explosion taking place..... there very very good starters normal...as 4 sparks at plugs....5th injector spraying neat Fuel in manifold...instant start..
