Hello. Here is the order of things for your truck. The engine firing order for either 4.6L or 5.4L V8 is 1-3-7-2-6-5-4-8. Cylinders are numbered, 1-2-3-4 on the passenger side bank of cylinders beginning at the front of the engine. Cylinders are numbered, 5-6-7-8 on the driver side bank again, beginning from the front of the engine to the back. Soooooooo the number 6 is the second one from the front of the engine on the drivers side.
you didn't say if you have the straight 6 or v 6.But i'll give the order for both.
The 4.9L straight 6 is 1-5-3-6-2-4----------- distributor rotor turning clockwise, and #1 plug is the first plug.
On the 3.0 and 4.2 V6 engines is 1-4-2-5-3-6-------#1 plug is the first plug on driver side---- facing engine.
you need the firing order?? it is 1, 6, 5, 4, 3, 2 clockwise. Number
one on cap is forward position, or 6 o'clock position, just left of the
hold down bolt.
The firing order for the 4.9 L engine is 1-5-3-6-2-4, with the firing order rotation on the distributor cap going clockwise. For the 5.0 & 7.5 L engines, the order is 1-5-4-2-6-3-7-8, and the 5.8 L engine is 1-3-7-2-6-5-4-8. On all three of these engines, the distributor cap firing rotation is counterclockwise. Also, on the six cylinder 4.9 L engine, the cylinders are in a "straight six", with #1 cylinder starting in front, and going in order straight back to #6. The eight cylinder engines' cylinders all fire in order also, (standing in front of the vehicle looking back towards the firewall) with #1 being front on your left and going straight back to #4, and then #5 being at front right, going straight back to #8, with the distributor being front and center. Hope this helps you out.
