Firing order on 99 dodge Dakota 3.9 v6

Assuming you know the basics of how an engine works the firing order is 1, 6, 5, 4, 3, 2.
Standing in front of the vehicle, facing the rear of the vehicle, the cylinder layout is this. Left side is the EVEN numbers and the right side is the ODD numbers. Number One is nearest to you on the right side. Number Two is nearest to you on the Left. Number 3 is the middle right, Number 4 is the middle left. 5 is back right and 6 is back left.
At the distributor the leads should be fitted in the firing order sequence moving in a CLOCKWISE direction. On some distributor caps the terminal for cylinder One is marked with a number on the top of the cap.
The cylinders Don't fire as pairs they fire in sequence alternating right to left.

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.

1984 pontiac bonnerville plug firing order photo

Hi,
I don't know your engine size, but the link below is a picture of the GM small block firing order with distributor.
The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
