Strange noise and solution

So I have a "ticking" sound on drivers side motor. I have checked the usual cam phaser and leaky header issue but that's not it. However, I noticed if I disconnect the front left injector( #5 cylinder?) it goes way(of course the engine runs a little rough as expected). As soon as its reconnected the loud ticking starts immediately. So a noisey injector you would think? But if the associated coil connector is dis connected with the injector connector still connected the ticking also goes away. The noise starts again after reconnecting the coil wire but not immediately...after 10 seconds or so when the cylinder gets un flooded I assume. So the loud ticking only happens when that cylinder is "firing".

Any ideas??
