Can a diesel run with no glow plugs?

Hey there! That's a really interesting question about diesel engines. From what I understand, diesel engines can technically run without glow plugs, but it really depends on the temperature and conditions. In warm weather, a diesel engine might start up just fine without glow plugs since diesel fuel ignites through compression heat alone. However, in colder weather, glow plugs are essential because they preheat the combustion chamber to help the fuel ignite properly. Without them in cold conditions, you'd likely have trouble starting the engine or it might not start at all. So while it's possible in some situations, glow plugs are definitely important for reliable starting, especially when it's chilly outside!
