The firing order for a 1978 Ford Bronco depends entirely on the engine it has. Ford Broncos in 1978 came with several different engines (inline-6, 302 V8, 351 V8, etc.). You
must know the engine displacement (e.g., 302 cubic inches) to determine the correct firing order.
Once you know the engine size, you can find the firing order in a repair manual specific to your Bronco's year and engine, or through an online resource like a Ford parts website or a dedicated automotive repair forum.
