The firing bespeak of an engine is the sequence the spark plugs fire. On engines through a distributor, the firing orderis identified by the routing that the spark plug wires from the distributor lid to the spark plugs in every cylinder.When the piston is at optimal dead facility (TDC) ~ above the compression stroke, the rotor inside the distributor need to be alignedwith the number one (#1) spark plug terminal in the distributor cap. Most Chrysler V8 distributors rotate in a clockwise direction, for this reason the next plug wire in the cap would certainly go to the next spark plugin the firing sequence for the engine.On many Chrysler engines the #1 cylinder is the very first cylinder in ~ the prior of the engine top top the driver side (left side) that a rear-wheel drive automobile or truck. Top top front-wheel drive cars and minivans v 2.7L and also 3.5L V6 engines, the #1 cylinder is the an initial cylinder top top the front ideal side of the engine. On trucks through the 3.9L V6, #1 cylinder is the an initial cylinder at the front LEFT of the engine.The cylinders room numbered in a staggered sequence, with all the odd numbers on one side and also the even numbers top top the other side.

The correct firing order is very important due to the fact that mixing increase the spark plug wires might prevent the engine indigenous starting, reason it come backfire and also run very poorly if in ~ all.On engines with distributorless ignition solution or coil-on-plug ignition systems, the firing stimulate is managed by the ignition module or engine computer. The computer receives an intake signal from the crankshaft position sensor (and camshaft position sensor on part engines) to identify which piston is comes up to top dead center on that is compression stroke. Itthen fires that spark plug, and the next and so top top in the firing sequence.
