Go to any parts store and ask them for a print out for your truck's firing order.

Not sure of your engine size so please pick the appicable diagram:

2.5L Engine Firing Order: 1-3-4-2 Distributor Rotation: Clockwise

3.9L Engine Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise

5.2L and 5.9L Engines Firing Order: 1-8-4-3-6-5-7-2 Distributor rotation: Clockwise

on the intake manifold it has the cylinders numbered 1432 and on the distributor it has the #1 pulg marked and will go in reverse directions so remove the cap if it has one and put the plugs on in order of the postion#1 on the distributroter then go 1342 if it has coils the coils pack will have numbers on the pack 12 34 so put the pulg wire on the way the coil is marked and the wat the intake is marked, there is only two ways it can be wired it's 1423 or 1234 so go for it. hope this helps.

What engine size are there: 4.3L V6, 5.0L V8 or 5.7L V8 ?

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.

I hope help you with this (remember rated this help) Good luck.

If you have the 3 cylinder engine, the firing order is 1/3/2. The distributor rotation is counter-clockwise looking at it from above, and the #1 spark plug wire goes on the distributor pin closest to the driver side fender.
If you have the 4 cylinder engine, the firing order is 1/3/4/2. The distributor rotation is also counter-clockwise, and the #1 wire goes on the distributor pin closest to the front passenger headlight.
Hope this helps!

Normally the firing order will be stamped on the top of the intake manifold also the number one plug will be the front one on the drivers side of the car. On the top of the distributor cap you should see a number one that is where the number one plug wire goes follow the firing order on the manifold and go clock wise on the distributor cap
