The 1993 Chevy 1500 V8 firing order depends on which engine was in it. There were several V8 options that year. You need to know the engine displacement (e.g., 5.0L, 5.7L, etc.) to get the correct firing order.
Once you know the engine displacement, you can find the firing order in your owner's manual or a reliable online repair manual specific to that engine.
