With the engine idling use a flare nut wrench and loosen each injector, listen for changes. If the idle changes move to the next injector, if no change than that is a bad injector. Grey diesel smelling smoke is either bad glow plug or bad injector, if it goes away when the engine warms up then it is a bad plug. You also might have an air locked injector which will not pop off right leading to a miss and grey smoke.
