Ford Taurus is equipped with 3.0L Duratec V6 engine, and the firing order is 1-4-2-5-3-6. The plugs are gapped at 1.3-1.4 mm (0.052-0.56”).
The firing order of an engine is the sequence the spark plugs fire. On engines with a distributor, the firing order is determined by the routing of the spark plug wires from the distributor cap to the spark plugs in each cylinder.
When the piston is at top dead center (TDC) on the compression stroke, the rotor inside the distributor should be aligned with the number one (#1) spark plug terminal in the distributor cap.
Most (but not all) Ford distributors rotate in a counter-clockwise direction, so the next plug wire in the cap would go to the next spark plug in the firing sequence for that engine.
