Firing Orders

Print


NOTE
To avoid confusion, always remove and tag all ignition related wires one at a time.

On 2.0L engines, if a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring may be the correct firing order, but could change the relative installation of the plug wires in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations.
