because it takes time to start a diesel engine
Starting a diesel engine is very different from starting a gasoline engine. While a gas engine starts when the spark plug ignites the fuel, diesel engines rely on the heat created by compression in the chamber. Sometimes, like during cold weather, diesel fuel needs the help of an outside heat source to reach the right temperature to start. When starting a diesel engine, you have three basic ways to do it: using an intake heater, using the glow plugs, or using the block heater.
Method 1 of 3: using an intake heater
One way to start a diesel engine is by using air intake heaters, which are located inside the intake manifold and heat the air as it enters the engine’s cylinders. By receiving its power directly from the vehicle’s battery, an intake heater is a great way to get the air temperature in the combustion chamber where it needs to be quickly, allowing you to start the diesel engine when you need it, with the benefit additional to do so. Eliminate white, gray, or black smoke that often occurs when the engine starts cold.
Step 1: turn the key.
Turn the ignition key to begin the diesel engine starting process.
Glow plugs are still used in this starting method, so you must wait for them to warm up before the vehicle can start properly.
The air inlet heater is designed so that the air entering the combustion chambers quickly reaches normal operating temperature.

Turn the key again and start the engine. Air inlet heaters use the energy produced by the battery when starting to heat the element installed in the air inlet pipe.
When the vehicle is started and the air passes through the heated elements, it enters the combustion chambers hotter than without the help of the air intake heaters.
This helps reduce or eliminate the white or gray smoke that is commonly produced when starting a diesel engine. This condition occurs when diesel fuel goes through the combustion process without burning and is the result of a combustion chamber that is too cold, causing less compression.
Method 2 of 3: using the glow plugs
The most common method of starting a diesel engine is by using glow plugs. Like an air intake heater, glow plugs are powered by the vehicle’s battery. This preheating process brings the air in the combustion chamber to a temperature conducive to cold starting.
Step 1: turn the key.
The “Wait To Start” light should appear on the dash.
Glow plugs can take up to 15 seconds to heat up or longer during cold weather.
When the glow plugs reach their normal operating temperature, the “Wait to start” light should go off.
Step 2: start the engine.
After the “Wait to Start” light goes out, try starting the engine.
Do not try to start the vehicle for more than 30 seconds. If the vehicle starts, release the key. Otherwise, turn the key to the off position.
Step 3: how to start a truck
reheat the glow plugs. Turn the key until the Wait to start light comes on again.
Wait for the light to turn off, indicating that the glow plugs are getting hot enough. This can take up to 15 seconds or more, depending on the temperature.
Step 4: diesel engine turns but won’t start
try starting the vehicle again. Once the “Wait To Start” light goes out, try to start the vehicle again.
Turn the key to the start position, cranking the engine for no more than 30 seconds. If the vehicle won’t start, turn the key to the off position and consider other options, such as using a block heater.
Method 3 of 3: using the block heater
If both the glow plugs and the air intake heater are not getting the air in the combustion chamber warm enough to start, you should consider using a block heater. Just like glow plugs heat the air inside the combustion chamber and the air intake heater heats the air as it enters the intake manifold, a block heater heats the engine block. This makes it easy to start the diesel engine in cold weather conditions.
