Spark plug wiring diagram

If the wires are still in the distributer, AND, if you have a stock intake manifold, the firing order is on the manifold. If it's a V-8, the number 1, 3, 5, & 7 plugs are on the drivers side of the engine. The number 2, 4, 6, & 8 plugs are on the passenger side. The number 1 plug wire can be located by looking at the distributer from the front of the engine and visually looking between the distributer and the number 1 plug. Visualize the distributer as a clock. The number one position should be located between 4 and 5 o'clock and should have the longest wire of those on that side of the distributer.

If the wires have been pulled from the distributer, then, then, remove the rotor cap, turn the engine over slowly until the rotor is pointing to the number 1 plug. Using the firing order on the intake manifold, starting with number 1, replace the wires going clockwise around the distributer.

not sure what you are hooking up...if you are putting on new spark plug wires...locate the distributor...usually marked #1 and goes in clockwise circle...firing order for the V8 is 18436572...hope that helps...usually changing one wire at a time is best...to not confuse the firing order...

Hope this is helpful.

Which ever plug you changed you need to follow that plugs wire to the dis. cap and that should be the wire. chrismoss

get a wiring diagram for the spark plug wires make sure there on right.. thats where i would start anyway..if there right check the plastic cover the plugs plug in to for a hairline crack.. if ok change plugs and wires.. and it should be fine

I can't upload the diagram but the firing order appears to be 1,4,6,3,2,5

Install the spark plug wire(s) (1, 3 and 5) to the engine right side spark plug(s).

Install the spark plug wire(s) to the retaining clips.

Install the spark plug wire(s) (2, 4 and 6) to the engine left side spark plug(s).

Install the spark plug wire(s) to the retaining clips.

You can get a copy of the service manual from Promanuals.net for cheap.

I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

3.9L V6 Engine. Engine Firing Order: 1-6-5-4-3-2. Distributor Rotation: Clockwise.............did i guess the right motor? let me know/rate me

Hope this helps, couldn't find diagram.

Firing order 1-8-4-3-6-5-7-2 --------------- | 2 4 6 8 | | | front | ----- | | | 8 || | | 1 4 || of | |2 3|| | | 7 6 || | | 5 || vehicle | ----- | | | | 1 3 5 7 | --------------- Distributor rotates clockwise

This is your best choice.Here is a diagram attached.
