Gas powered engines and diesel powered engines ignite differently. Gas powered engines start when the fuel is ignited by a spark from a spark plug. In contrast, diesel engines are ignited by the heat caused by compression. In a diesel truck, the fuel and air must get hot enough to create combustion, which then creates the spark to start the engine. Because heat is necessary to start a diesel truck, the process for starting it is different than starting a gas engine. Follow these steps to start a diesel truck.

Steps

  1. Step 1 Turn the key to the start position without turning the engine on.
    You will see the "wait to start" light on the dash. Do not attempt to start the engine until the light disappears.
  2. Heating the glow plugs takes up to 15 seconds. The "wait to start" light won't go out until the glow plugs are ready. During cold weather, the glow plugs will take longer to heat.[1]

Warnings

  • Never use starting fluid on your diesel truck. Starting fluid is for gas engines only and (could harm your truck's pistons or combustion chamber.(If using starting fluid use with caution glow plugs and intake heaters will cause it to ignite early and blow the heads off.)

  • Diesel fuel will turn into a gel at temperatures of below -6 to -18 degrees Celsius (21.2 to -.399 degrees Fahrenheit). The engine won't start because the fuel is frozen. If you are in an area with temperatures below these ranges, get your diesel fuel at a gas station that uses additives in the diesel that lower the freezing point of the fuel. The other option is to buy an additive at a truck stop in the area.
    Thanks
