Got a 445 John Deere that won't fire right cylinder. Installed new coils from John Deere new caps for sparkplugs new plugs all without making a change . Checked compression , 170 is min. I'm at 198 . Checked valve settings - ok. Checked while running by spraying gas down the throat and the cylinder came alive . Thinking electronic injector could be the problem so changed out throttle body complete with "known to be good" unit as the JD tech manual advises, no change . Was wondering if anyone could tell me if the pulsar coil which signals the injector is sequential alternating left and right signals to injector or it just fires every time the mag comes around on the flywheel ? Anybody got any ideas ? Any help would be appreciated.
