3 8 Buick Turbo Engine Coil Pack Firing Order Spark Plug Wire Location

sitting on bike the left coil plugs to 1 and 3 , the right coil plugs 2 and 4,this is a wasted spark ignition , both cylinders recieve spark but only one is on the compression stroke

On Ford engines the passenger front is #1 or firewall side then count back sequentially 1,2,3,4 drivers bank 5,6,7,8, So the last cylinder next to the transmission is #4 firewall side and the second one back is #6 on radiator side.

STANDING FRONT OF VECHICLE CYLINDERS FACING YOU ARE 4 5 6 AND BACK CYLINDERS IS 1 2 3 NOW ON PIECE PAPER LOOKING AT IGNITION COIL PACK FACING YOU WRITE BACK NUMBERS 123 AND UNDER THAT NUMBER 1 2 3 WRITE FRONT NUMBERS 5 6 4 THATS YOUR COIL PACK PLUG WIRES LOCATION. LIKE I SAY 5 6 4 IS PLUGS WIRES LOCATION FACING YOU AND BACK NUMBERS 1 2 3 PLUG WIRES LOCATION ON COIL PACK. FIRING ORDER IS 1 4 2 5 3 6

First, remove the no. 1 engine cover. Locate the ignition coils, these will be squarish-looking packs with spark plug wires (4 of them) coming out. The wires should be going to the spark plugs, which are on the front and back side of the engine.
Grab the ignition coils or spark plug wires by the thick plastic piece at the end of the wire. Squeeze the end and turn it to release it from the spark plug. Pull back to remove the plug from the engine.
Slide the spark plug socket over the spark plug. The most common size of spark plug socket used on a Toyota Highlander is 16mm. Turn the socket to the left to unscrew and remove the spark plug from the cylinder well.

HI. Your spark plugs are located and inserted into each cylinder location, just under the respective ignition coil. This engine is designed for a Coil on Plug setup. The ignition coils are attached to each plug in the engine. Once you have removed each plugs respective coil,which is located directly on top of each plug, Then will you notice the plug. When removing the front plugs, be sure to remove the intake manifold to gain full access.

NOTE- Always remove the ignition coil assembly by grasping at the spark plug boot, turning the assembly 1/2 turn and pulling straight back in a steady motion. Only then will you gain access to the plug that is placed in that particular cylinder.

1. Spark plugs removal

1.1. Front cylinder bank spark plugs removal:
1.1.1. Disconnect the battery from car terminals.
1.1.2. Remove the engine plastic cover.
1.1.3. Disconnect the ignition coils electrical supply cable and all three coils connectors.
1.1.4. Remove all three ignition coils screws.
1.1.5. Remove all three ignition coils out from cylinder head.
1.1.6. Remove all three spark plugs out from cylinder head (straight forward).

1.2. Back cylinder head bank spark plugs removal:
1.2.1. Remove the inlet manifold out from cylinder head.
1.2.2. Disconnect all three ignition coils connectors.
1.2.3. Remove all three ignition coils screws.
1.2.4. Remove all three ignition coils out from cylinder head.
1.2.5. Remove all three spark plugs out from cylinder head (straight forward).

2. Spark plugs installation

2.1. Refit all in reverse order.
2.2. Spark plugs tightening torque = 2,8 +/- 0,3 daN.m
2.3. Ignition coils tightening torque = 0,8 +/- 0,2 daN.m

The firing order is 1-8-7-3-6-5-4-2 and the #1 cylinder is located at the left front of the engine and the spark plug and ignition coil for the #1 cylinder will be the first ignition coil and spark plug on the front of the left side of the engine on top of the valve cover, and to remove an ignition coil dis-connect the wire connector to the ignition coil, then remove the bolt securing the ignition coil (usually this is one 10 mm bolt) and give the ignition coil a twist as you pull it straight up and out of the spark plug well, and if you are removing the spark plug then use a socket with an extension and swivel to loosen up and tighten the spark plug, but use about a 6 inch length of 3/8 inch fuel line pushed onto the spark plug to actually remove the old spark plug and also to start the new spark plug down inside of the spark plug well to reduce the possibility of cross-threading or damaging the threads for the spark plug. Here are some images to assist you and the ignition coil location image shows the right side of the engine for reference, with cylinders 2-4-6-8 and this was just the best image that I could find to make that diagram, however they are laid out the same on the left side of the engine 1-3-5-7, and let me know if you require any further assistance.

unlike the front spark plugs which are under the little plastic cover, the rear spark plugs are located almost against the fire wall. they are not covered by the same as the front. there are little green clips that hold on to the ignition coils, locate those. they are in between the intake manifold. directly below are small bolts that hold down the the spark plug wires (connected to the little green clips) remove the bolts and pull out the coil pack. you will need the same size extension as you needed on the front. hope this helps

Your spark plugs can be located in 2 different locations.
1 if your engine is sitting front to back of the vehicle your plugs will be located on the drivers side and the passengers side of the vehicle.
2 if your engine is set from one wheel well to the other than your spark plugs will be located on the front of the engine ( front towards the bumper/grill.) and next to the firewall.

4.6L, 5.4L & 6.8L Engines

7. 
   

installation.

1. Install the spark plugs and tighten them to 13 ft. lbs. (18 Nm) for 4.6L and 5.4L SOHC engines. For 5.4L DOHC and 6.8L engines, tighten the spark plugs to 15 ft. lbs. (20 Nm).
   
2. Install the coil on plugs.
