Error code 224 I replaced one coil, the spark plugs and wires. No spark from 2 of the front coil connectors

please tell me in this tune up you had new spark plugs put in? if check engine light is on there are some stored codes those will give you the suspect cylinder(s) check to see if you have plug wires if not there will be a coil for each cyl. pass. side of motor starting in the front working to the back or firewall cyls are 1,2,3,4 driver side same front to back 5,6,7,8 codes will be PO301 cyl 1. PO302 cyl 2. etc. get the code find the correct cyl. unplug little connector u will need a 7mm socket to remove the bolt holding the coil in place then pull up on the coil and boot.... if u have plug wires get the code find correct cyl and follow plug wire to coil pack in front of engine there will be two one on each side in front of engine...

The spark plugs are located in the valve covers dwon in wells under the individual ignition coils,(8 of them), the coils have a 2 wire connector going to them, careful unlatch the connector lock and remove the connector male end, then remove the on 8mm machine screw that retains each coil to the valve cover stand off, only do one at a time, twist the coil back and forth to break the bond of the rubber boot to the spark plug insulator and gently pull up while you do this, DO NOT FORCE IT or you will have to replace the coil assembly to get a new boot. The job takes about 2-3 hours.

FRONT AND BACK JUST FOLLOW THE WIRES THERE THICK AND BLACK AND THERE,S SIX OF THEM AND THATS WHERE YOUR SPARK PLUGS ARE

Hi,
REMOVAL
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.

• Prior to removing the spark plug, spray compressed air around the coil area and spark plug.
• Remove electrical connector from ignition coil.

On 3.5L engines, it is necessary to loosen the screws by alternating back and forth. Do not lose the spacers under the coil when loosening the screws.

• Remove 2 fasteners from ignition coil.
• Remove ignition coil assembly.
• Remove the spark plug using a quality socket with a rubber or foam insert.
• Inspect the spark plug condition.

INSTALLATION
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.

• To avoid cross threading, start the spark plug into the cylinder head by hand.
• 3.5L engines tighten spark plugs to 28 N·m (20 ft. lbs.) torque, 2.7L engine tighten spark plugs to 17.6 N·m (13 ft. lbs.).
• Install ignition coil assembly onto spark plug.
• Install coil screws and tighten: 2.7L engine to 6.2 N·m (55 in. lbs.), 3.5L engines to 6.7 N·m (60 in. lbs.).
• Connect the electrical connector.

There are no spark plug wires on the 2000-up Northstar engines. They use coil on plug design. First remove the engine service cover.(The Pretty plastic peice that has the Cadillac symbol on it) Then disconnect the coil connector which sits to the right of the coil and should just snap off by hand. Next If you remove the screws that holds the coil pack (8 screws) to the top of the cam covers, you will see 4 black round rubber boots that sit on top of the plugs. Pull the boots free to expose the plugs. The tops of the spark plugs sit directly underneath

On the V6 engine The drivers side plugs are easy although the passenger side will require you to remove the intake boot and the coil packs, easily done with a 10 mm socket and ratchet. Disconect the coil pack connectors by depressing the plastic clip and pulling them off one by one on the three coil packs . leave the plug wires attached and pull the coil pack straight up and off the spark plug.Blow out the area around the plug with compressed air to prevent debris from entering engine when the plugs are removed. Use a 5/8 spark plug socket and a 8 inch extension bar on your 3/8 ratchet at remove the plugs. use anti seize on the new plugs, gap the plugs to manufacturer specs and install your new plugs 2. If its a 4 cyl engine its actually a bit more difficult. The intake boot assembly has a bracket that bolts to the valve cover and side of the engine and you must remove it to access the 4 coil packs on top of the engine. once again the coil pack wires must be disconected and the coil packs un bolted and removed from the valve cover to access the plugs. Blow all dirt from around plug with compressed air to prevent foreign objects or dirt from entering the engine when you remove the spark plug , once again use a 3/8 ratchet and an extension with your 5/8 spark plug socket and remove plugs, use a small amount of anti seize compound on the threads of the nes plugs and gap them to manufacturer specs before installation. Also while the coil packs are off,, Inspect them for ARC Tracing a white residue and line may form on the coil pack Tip/boot if you see alot of ARC tracing Id suggest replacing that coil pack. Especially if you have a misfire condition.

the coil pack mybe bad

Changing Spark Plugs

First off, on this model you don't have plug wires, you have coil packs with a boot and coil connected to the pack. The boot slides on the tops of the spark plug. The good thing about this is that you don't have to mark each wire to its location.

So to replace the plugs you need to disconnect the electrical connector to the coil pack and then unbolt the two bolts that mount the pack down, then remove the pack.

Next with a ratchet, an extension and a special spark plug socket, which has an insulator inside to protect the porcelain from getting cracked, remove the spark plugs.

Next step is to replace the plug, usually I slide off the boot from the coil pack and then remove the coil from inside the boot and slide the boot over the spark plug and start to thread the plug back in. Using this method allows to you feel if you are threading the plug in right. Then with a torque wrench you would torque the spark plug to the specs for the type of engine you have.

3.2/3.5L Engine (20 ft-lbs)
2.7L Engine (13 ft-lbs)

Next reinstall the coil pack with the two mounting bolts, it is only necessary to hand tigthen the two bolts. Then plug back in the electrical connector and continue this process on the next 5 spark plugs.

Changing Dome Light

To remove the map light bulbs you need to first remove the overhead console.

To do this you need to remove the screw at the front of the overhead console (which is more towards the front windshield).

Next you need to pry down on the rear of the overhead console and then disconnect the electrical connectors.

Then, with the overhead console pulled down, pull of the map light bulbholders and replace the bulbs.

Installation is the reverse of the removal process.

To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine:
Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way.
Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed.
Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right.
Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place.
To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place.
Repeat same procedures for spark plugs number (3) and (4).
Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold.
