I need the firing sequence on the 1994 GMC Sonoma from spark plugs to the distributor cap. My brother got the wires mixed up...he doesn't know where the wires go.


Here is the firing order diagrams for the 4.3 liter V-6 engine and the 2.2 liter 4 cylinder engine, and let me know if you need any help to understand these diagrams, or if you require any further assistance.

4.3 Liter V-6 Engine.

I changed my spark plug wires and possibly have them connected wrong. Is there a schematic that I might follow in order to ensure they are connected correctly?


FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers 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. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1988-95 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g01.gif
Fig. 2: 1996-98 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g02.gif

Need firing order to 89 chevy s-10 p/u w/ 4.3 liter/6cyl. replacing plug wires


4.3 v/6 firing order for an S-10 Chevy is 1-6-5-4-3-2, a helpful tip to always locate # 1 spark plug on a v engine.
If you look carefully at the cylinder heads note the very front of each, do you see one sticks out slightly further to the front then the other?
Tghis is the way these engines have to be cast for proper cylinder and timing rotation.
The furthest forward cylinder head is in fact the home of #1 cylinder, it is the first spark plug on that head, which in this case is the right side head.
