The only exception is the Nissan V6 in the Probe and Villager, which are numbered in a staggered sequence similar to a GM engine. The cylinders are numbered in sequence starting with the #1 cylinder going towards the back of the engine on each cylinder bank (see illustrations below). On front-wheel drive cars and minivans with a transverse (sideways) mounted V6, the #1 cylinder is the first cylinder on the rear side of the engine on the passenger (right) side. On most Ford engines the #1 cylinder is the first cylinder at the front of the engine on the passenger side (right side) of a rear-wheel drive car or truck. The distributor rotates clockwise on Ford V6 and straight 6-cylinder engines, and also clockwise on Ford 2.0L and 2.3L four-cylinder engines. Ford V8 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. With the number one (#1) spark plug terminal in the distributor cap. When the piston is at top dead center (TDC) on the compression stroke, the rotor inside the distributor should be aligned Is determined by the routing of the spark plug wires from the distributor cap to the spark plugs in each cylinder.

On engines with a distributor, the firing order The firing order of an engine is the sequence the spark plugs fire. Auto Repair Library, Auto Parts, Accessories, Tools, Manuals & Books, Car BLOG, Links, Index
