The firing order for a Dodge B3500 Ram van depends entirely on the engine it has. Dodge B3500 Ram vans came with a variety of engines over the years (V6, V8, different displacements). You
must specify the engine's displacement (e.g., 5.2L, 5.9L, etc.) and year to get the correct firing order.
Once you provide that information, I can look it up for you.
