Ok are actually seeing that the plug isn't firing or did you replace the plug and the cylinder is still dead ? .have you checked distributor cap /rotor ? Is it just one spark plug not firing or none firing ? Maybe more information from you would make it easier to help answer your question and get you back on the road ..

99 is a split year. Do you have a 5.7 vortec motor? Or a 5.3 ls motor?
