are the leads/coil extensions ok? are you certain you dont have a faulty injector?

check the resistance of the plug lead and compare it with the others,if its open circuit or higher in resistance than a longer lead then replace it .they are normally about 3000 ohms per foot of lead

remove coil pack. place old set of plugs in the ends and turn the engine over. check all are actually firing... if they are the check signal at injector with a noid light. if present then only thin left is a compression check of all cylinders
