Where would you spray starter fluid in a diesel truck?

You should never spray starter fluid into a diesel engine. Diesel engines rely on compression ignition, not a spark plug and easily ignitable fuel like gasoline. Spraying starter fluid into a diesel engine is incredibly dangerous and can lead to:

* Serious injury: The highly flammable starter fluid can explode in the combustion chamber, causing severe damage to the engine and potentially injuring anyone nearby.

* Engine damage: The sudden, uncontrolled combustion can severely damage pistons, connecting rods, and other internal components.

* Fire: The highly flammable nature of starter fluid presents a significant fire risk.

If your diesel truck is having starting problems, do not use starter fluid. Instead, diagnose and address the underlying issue, such as a faulty glow plug system, low compression, fuel delivery problems, or a weak battery. A qualified mechanic should be consulted to properly diagnose and repair the problem.
