Code P1369 means either 5 or 6 is bad. I would doubt that both are bad. The resistance reading for a glow plug is 3 ohms perhaps, so if your ohmeter is set to a high range, it may just show up as zero. A bad GP will read infinity. It's like a light bulb...it's either good or bad. Any metal that is connected to engine or frame is good to use as a ground.
