The firing order for a 1984 Chevy truck depends entirely on the engine it has. Chevrolet trucks in 1984 used a variety of engines. To determine the firing order, you
must know the engine's displacement (e.g., 2.8L, 4.3L, 5.0L, 5.7L, 6.2L, etc.).
Once you know the engine size, you can find the firing order in a repair manual specific to your truck's year and engine, or through an online resource like a vehicle-specific forum or a website dedicated to engine specifications.
