The firing order for a 1986 Chevy Suburban depends entirely on the engine it has. Suburbans in 1986 came with several different engine options (e.g., small-block V8s, a large-block V8, and possibly a diesel). You
must know the engine displacement (e.g., 5.0L, 5.7L, 6.2L, 6.5L) 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 Suburban's engine or through online resources like engine repair websites or forums.
