White smoke is signs of air leakage into the cylinder. With 5 good injectors, it wont produce enuf white smoke to see. What yr model is it? Before 03, it should individual lines goin to ea injector, u can loosen off on ea injector line till u dont hear a diff in eng sound, ie: labor knocking or more rough ideling. If u cone across an injector line that doesnt make it sound or idel diff, thats ur bad injector. Its called a cylinder cut out test. Pull that injector n have them test it, it should hav between 16,000-20,000psi for normal operation. To little psi n its not opening, to much n its blowing to much fuel.
