Glow Plug

Car came in with a glow plug fault, all glow plugs ohmed good so I decided to compare a cylinder with no fault to the one with a fault, both were the same. I wish I had captured the crank or cam signal at the same time, because the glow plug module will run the plugs after the vehicle is started as well.
