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)

How do you change spark plugs in a 2004 hyundia sonata


It depends on which engine is in the vehicle. The 2004 Sonata came with two possible powertrains -- the 2.4 Lit L4, and the 2.7 Lit V6.

On the 4 cylinder engine, there are two coil packs and two ignition wires, Below each coil pack is a spark plug (#2 and #4 cylinders). The wire from # 2 coil pack goes to #3 spark plug, and the wire from #4 coil pack goes to #1 spark plug.

Now the 2.7 Lit V6 requires you remove the surge tank (intake manifold) in order to access the spark plugs & wires on Bank 1 (Right Hand side of the engine).

Do i have a coil pack


Vehicles either have a distributor for mechanically controlled igntion timing or are distributorless and have coil packs or individual ignition coils which are electronically controlled by the vehicles electronic control module or a powertrain control module. Simply look at your engine's cylinder head and see if the plug wire goes into a distributor cap or into a coil pack (which looks like a small block with other plug wires attached as well)

#1 cylinder not firing


you need to check compression on that cylinder if it is ok the coil pack could be bad disconect number 1 wire from the coil pack hold a screwdriver with a plastic handle near the hole where the wire goes in and see if there is spark coming out of the coil pack if there is you just might have a bad wire if there is no spark there change the coil pack

Were is the ignition module located at do you have a pic or diagram


Ignition control module is located under the ignition coil packs, follow the spark plug wire''s from engine to coil packs.
If you have a 3.1L engine, the module will have three connector, two one one end and one in the other end.
If you have a 3.8L engine, the module will have one wide connector on one end only.
To remove module, remove all three coil pack's, will have two small screw's to each one,disconnect elec. connector from module and unbolt module.

These cars do have problems with coil packs, have you replaced these yet, if not then i would advise this be your next step. If you can get the ignition plate that goes under the coil packs also.
