The firing order of one engine is the sequence the spark plugs fire. Top top engines through a distributor, the shooting orderis established by the routing of the spark plug wires indigenous the distributor lid to the spark plugs in each cylinder.When the piston is at optimal dead center (TDC) on the compression stroke, the rotor inside the distributor should be alignedwith the number one (#1) spark plug terminal in the distributor cap. Most Chrysler V8 distributors rotate in a clockwise direction, so the following plug cable in the cap would certainly go come the following spark plugin the firing sequence for the engine.On many Chrysler engines the #1 cylinder is the very first cylinder at the former of the engine top top the driver next (left side) the a rear-wheel drive vehicle 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 ~ above the front ideal side that the engine. ~ above trucks through the 3.9L V6, #1 cylinder is the very first cylinder in ~ the front LEFT the the engine.The cylinders are numbered in a staggered sequence, with all the odd numbers on one side and the also numbers ~ above the other side.

The correct firing stimulate is really important due to the fact that mixing increase the spark plug wires may prevent the engine native starting, reason it to backfire and also run really poorly if at all.On engines with distributorless ignition systems or coil-on-plug ignition systems, the firing bespeak is managed by the ignition module or engine computer. The computer system receives an intake signal indigenous the crankshaft position sensor (and camshaft position sensor on part engines) to identify which piston is coming up to height dead center on its compression stroke. Itthen fires the spark plug, and the next and so on in the shooting sequence.
