The firing bespeak of one engine is the succession the spark plugs fire. On engines through a distributor, the shoot orderis determined by the routing of the spark plug wires from the distributor lid to the spark plugs in each cylinder.When the piston is at optimal dead facility (TDC) on 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 revolve in a clockwise direction, for this reason the next plug cable in the cap would go come the next spark plugin the firing succession for the engine.On most Chrysler engines the #1 cylinder is the very first cylinder in ~ the former of the engine ~ above the driver side (left side) that a rear-wheel drive car or truck. Top top front-wheel journey cars and minivans with 2.7L and 3.5L V6 engines, the #1 cylinder is the first cylinder on the front best side that the engine. On trucks through the 3.9L V6, #1 cylinder is the very first cylinder at the former LEFT that the engine.The cylinders space numbered in a staggered sequence, through all the odd numbers on one side and the also numbers ~ above the other side.

The exactly firing bespeak is very important due to the fact that mixing up the spark plug wires may prevent the engine from starting, reason it come backfire and run an extremely poorly if at all.On engines through distributorless ignition equipment or coil-on-plug ignition systems, the firing stimulate is controlled by the ignition module or engine computer. The computer receives an intake signal indigenous the crankshaft place sensor (and camshaft position sensor on part engines) to determine which piston is comes up to height dead facility on the compression stroke. Itthen fires that spark plug, and the next and so top top in the firing sequence.
