QUICK ANSWER

The 1JZ-GTE Inline-Six firing order is 1-5-3-6-2-4. Cylinder 1 sits at the timing/front end and the cylinders count consecutively to number 6 at the transmission end.

Application note: Covers the production 1JZ-GTE inline-six mechanical sequence, including common non-VVT-i twin-turbo and VVT-i single-turbo versions.

The 1JZ-GTE Inline-Six firing order is 1-5-3-6-2-4. Cylinder 1 sits at the timing/front end and the cylinders count consecutively to number 6 at the transmission 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.

Do not assume the same coil control or trigger wiring across JZX revisions. Confirm non-VVT-i versus VVT-i, ECU and harness identity before electrical diagnosis; the mechanical sequence alone does not define ignition-channel wiring.

Which 1JZ-GTE Inline-Six firing order applies?

Covers the production 1JZ-GTE inline-six mechanical sequence, including common non-VVT-i twin-turbo and VVT-i single-turbo versions. 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 1-5-3-6-2-4 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.
