Honda B16A Firing Order and Distributor Diagram
Honda B16A Firing Order and Distributor Diagram with 1-3-4-2, physical numbering, identification cautions and routing procedure.
The B16A Inline-Four firing order is 1-3-4-2. Cylinder 1 sits at the timing-belt end, followed by 2-3-4 toward the transmission/distributor end.
The B16A Inline-Four firing order is 1-3-4-2. Cylinder 1 sits at the timing-belt end, followed by 2-3-4 toward the transmission/distributor end. A firing order is the sequence in which the cylinders begin their power strokes. It is not the same thing as cylinder numbering, distributor-cap clock position, or ignition-coil connector order. Confusing those references can create a no-start, violent backfire, dead cylinders, or a diagnostic trail that looks like a fuel or mechanical problem.
Use the verified order only after identifying the engine family and camshaft. Classic engines can accept camshaft swaps that change the required sequence, while modern coil-on-plug engines have no distributor cap to route. The table, bank diagram, and procedure below keep those concepts separate and show how to confirm No. 1 on compression before moving any wires.

Select each cylinder to walk through the firing order. Cylinder-bank numbering and distributor direction must match the identified engine family.

| Physical numbering | Cylinder 1 sits at the timing-belt end, followed by 2-3-4 toward the transmission/distributor end. | Orient by the timing/front end |
Do not choose a cap tower only from its physical height or a photo of another distributor. Confirm cylinder 1 on its compression stroke and the rotor-facing terminal, then follow the correct distributor rotation and exact manual for the installed unit.
Which B16A Inline-Four firing order applies?
Covers Honda B16A-family distributor engines while recognizing that distributor and ignition-control hardware changed across OBD generations and markets. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.
The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-3-4-2 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
