The firing order of an engine is the sequence the spark plugs fire. On engines through a distributor, the shooting orderis determined by the routing the the spark plug wires native the distributor cap to the spark plugs in each cylinder.When the piston is at peak dead facility (TDC) on the compression stroke, the rotor within the distributor should 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 following spark plugin the firing succession for that engine.On many Chrysler engines the #1 cylinder is the first cylinder in ~ the front of the engine top top the driver next (left side) that a rear-wheel drive vehicle or truck. ~ above front-wheel drive cars and minivans v 2.7L and 3.5L V6 engines, the #1 cylinder is the an initial cylinder top top the front appropriate side of the engine. ~ above trucks through the 3.9L V6, #1 cylinder is the first cylinder at the former LEFT of the engine.The cylinders room numbered in a staggered sequence, v all the odd number on one side and also the even numbers on the various other side.

The correct firing bespeak is really important because mixing up the spark plug wires might prevent the engine indigenous starting, reason it come backfire and also run really poorly if at all.On engines v distributorless ignition systems or coil-on-plug ignition systems, the firing bespeak is regulated by the ignition module or engine computer. The computer system receives an entry signal from the crankshaft place sensor (and camshaft position sensor on part engines) to determine which piston is comes up to peak dead facility on that compression stroke. Itthen fires that spark plug, and the next and also so ~ above in the firing sequence.
