Yes, it will make it harder to start the car if one plug is bad. IIRC, the engine will run rough for a bit until that cylinder gets warm enough to fire. If yours is running smoothly from moment it finally starts, then I don't think it's a single (or two) glow plug issue. Either a bad plug relay or fuse, or low compression. YMMV.
