2000 Pontiac Grand Prix V6 Firing Order Diagram 1-6-5-4-3-2 & Coil Pack Layout

This document is a simple ignition schematic showing the firing order for a transverse-mounted V6 engine. The firing order is stated as 1-6-5-4-3-2. The diagram depicts two cylinder banks: the top (rear) bank contains cylinders 2, 4, and 6, while the bottom (front) bank contains cylinders 1, 3, and 5, with cylinder 1 emphasized in bold. Below the cylinder layout is a vertical illustration of the coil pack or ignition module towers with three coil circles, showing spark plug wire terminal positions labeled from top to bottom as 6, 3, 2, 5, 4, and 1. The label 'Front of Vehicle' at the bottom orients the diagram, indicating a transversely mounted engine with the 1-3-5 bank toward the front of the car. The document was uploaded to a gallery for a 2000 Pontiac Grand Prix, consistent with a GM 60-degree or 3800 V6 layout, though the document itself contains no year, make, model, or engine identification. A reader can use this diagram to correctly route spark plug wires from the coil pack terminals to the appropriate cylinders and to identify cylinder numbering for diagnostics.
