FIRING ORDERS
To avoid confusion, ALWAYS replace spark plug wires one at a time.
The most important thing to remember about the removal and
installation of a distributor, cap or spark plug cable is that all
wires MUST be labelled before they are disconnected. Keep in mind that
these figures depict a firing order where the distributor cap terminals
are relative to EACH OTHER only and they do not necessarily depict the
tower positions in relation to the rest of the engine. This is true
because any distributor which has been removed and reinstalled may have
been installed with the No. 1 spark plug tower at any position (360
degrees) in relation to the rest of the motor, as long as the rotor
aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the
compression stroke (valves closed, ready for the plug to fire). As long
as the remaining wires were connected in the correct firing order
sequence (depending on direction of distributor rotation) the engine
will run. DO NOT EVER remove more than one wire from the distributor
cap at a time unless you tag ALL wires and towers to assure proper
installation.
