Mitsubishi 4G63 Firing Order and Cylinder Diagram
Mitsubishi 4G63 Firing Order and Cylinder Diagram with 1-3-4-2, physical numbering, identification cautions and routing procedure.
The 4G63 Inline-Four firing order is 1-3-4-2. Mitsubishi numbers the cylinders 1-2-3-4 from the front/timing-belt side toward the transmission.
The 4G63 Inline-Four firing order is 1-3-4-2. Mitsubishi numbers the cylinders 1-2-3-4 from the front/timing-belt side toward the transmission. 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 | Mitsubishi numbers the cylinders 1-2-3-4 from the front/timing-belt side toward the transmission. | Orient by the timing/front end |
Keep the mechanical order separate from coil pairing and ECU output order. Wasted-spark systems, later coil-on-plug conversions and different cam-angle-sensor/ECU generations require the diagram for the installed application.
Which 4G63 Inline-Four firing order applies?
Covers the factory mechanical firing order of common naturally aspirated and turbocharged 4G63 inline-four engines; ignition hardware varies by model and generation. 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.
