If one or more glow plugs have burned out, are carbon fouled or damaged, the engine will become progressively harder to start as temperatures drop and will idle roughly and produce white smoke from the exhaust for several minutes once it finally starts. If all the glow plugs are burned at their tips, check the fuel injection timing. 4.
What should I do if my 6.5L engine won’t start?

Why does my diesel truck not start when plugged in?
When the glow plugs or intake heater aren’t working properly, your truck won’t start because there’s no combustion. Plugging the truck in will allow the block heater to create the heat necessary for combustion to start the truck. Leave the truck plugged in for at least 2 hours before you try to restart the vehicle.
Can a diesel engine start without a glow plug?
A diesel engine cannot start and operate properly without the heat generated from this plug. If you normally drive your diesel-powered vehicle in colder environments, your engine will rely on the diesel glow plug to generate the necessary heat it needs to function.

What causes a glow plug to go out?
This ignites the diesel fuel, resulting in combustion. Misfires can be caused by issues with fuel quality, compression and fuel injection. The combustion chamber heat comes from compression pressure and glow plug heat. It needs to reach at least 450° F / 232° C for ignition to take place.
How long does it take for the glow plug to warm up?
