I am having trouble fiquiring out which wire goes to which plug. The wires are different lengths and the correct wire length has to go specifically with the correct plug. I have the firing order dia


The firing order is 1-2-3-4-5-6
Cyl #1 is front left when looking at engine front to back
left coil pack connects to cyls. 5-2
center coil pack connects to cyls. 3-6
right coil pack connects to cyls. 4-1
It doesn't matter which connector on the coil you use just that the cylinder is connected to the proper coil pack (the coil fires both plugs at the same time, twice per each full 4 stroke cycle)

The numbers to the cylinders are on the coil packs. Standing on the passenger side of the car looking at the engine, the right side is 1, 3, 5 cylinders. On the left is 2, 4, 6 cylinders. Put the correct number cylinder plug wire on the correct number coil pack. The 1,3,5 cylinder plug wires will go on the right side of the coil pack, and the 2,4,6 will go on the left. They will not be in order on the coil pack, so double check the cylinder number.

2004 KIA OPTIMA WON'T START AFTER SPARK PLUGS WERE CHANGES


HI. There are several areas of concern here. I will list them below. Check all areas stated in the list for faults.

Possible cuases:

1. Incorrect firing order set. On the 2.0, 2.4 and 2.7 engines. These engines are equipped with a distributor-less ignition system. This system incorporates a coil pack assembly, along with wire sets. In order for the assembly to fire correctly, the order of the wires must be set to the proper sequence. if not, the engine will not turn over, or start correctly. Make sure your firing order is correct, and make sure you have not placed a particular wire set into the wrong cylinder. I will post a picture of the correct firing order for your engine, below this list, shortly.


2. Incorrect spark plug gapping procedure. If the new spark plugs were gapped incorrectly, this will not allow for proper spark, thus, preventing optimal combustion, due to lack of fire. Check the spark plug gap using a wire gap gauge, and adjust if necessary. The gap should be 0.039-0.043 in. (1.0-1.1mm)

3. Failed coil pack assembly. This will be the worst case scenario. The coil pack supplies the necessary current that fuels each plug. The current is transferred, via wire sets.This will be the culprit if all the above areas are proven to be operational, and in good shape.

4. Failed wire sets. Replace the wire sets if faults are found at the connector at the ignition coil pack, or at the plug boot.



NOTE*
In order to provide the correct firing order for your engine, i will need the engine size and liter information, if possible. Please post this information, asap. Thanks..
