First off, drain the coolant as the injection nozzles fit in a brass sleeve which is directly exposed to the coolant so if sleeve loosens you may end up with cyl full of coolant. Second, don't twist back and forth as this will only make them bind tighter. They should actually just pull out easily if top dirt seal and lower compression seal are good. Usually just a small rolling head bar will pop a tight one out but you may have to devise a puller. Before installing them clean sleeve good including the hole in bottom where tip extend into comb chamber and try fitting injector into sleeve with out the top seal to make sure it drops right into bottom on it's own weight. I have seen them where they leak combustion after installation due to the carbon build up in that hole and injector not bottoming out really easy. Torque clamping cap screw to only 12 ft lbs .
