Coil pack might have just went out those thing go out all the time if you check the resistance across the coils you can tell if they are bad. im not sure the exact resistance they are supposed to be but if it reads open its bad for sure. If you pick up a haynes manual for your car it should have the correct resistance in there they are only like fifteen dollars and are a very useful tools its a must have if you do any work on your car.

Cant find plugs on a 3.7 6 cylinder 2 wheel drive dakota please help


3.7L Engines
Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation. Prior to removing spark plug, spray compressed air around base of ignition coil at cylinder head. This will help prevent foreign material from entering combustion chamber.

  1. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert.
  2. Inspect spark plug condition.
To install:
  1. Start the spark plug into the cylinder head by hand to avoid cross threading.
  2. Before installing coil(s), check condition of coil o-ring and replace as necessary. To aid in coil installation, apply silicone to coil o-ring.
  3. Tighten spark plugs to 27 Nm (20 ft. lbs.) torque.
  4. Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

Not getting spark


need more info (need to know what type of ignition system your vehicle has: (1) traditional ignition coil /distributor system, or (2) electronic ignition, but lack of spark problems are usually a faulty coil
on traditional vehicles, and on the newer electronic ignition cars, total lack of spark would be
a faulty ECM (electronic control module) - partial lack of spark (diagnosed with a HEI (high energy ignition) spark tester kit), would be caused by a faulty coil pack (in the waste spark system), where
there's 1 coil pack for every 2 spark plugs.
I bought my HEI igntion testere kit for $20, but Harbor Freight sells a similar unit for $10.
Hope this helps.

How do you replace the spark plugs on a 1998 2.7 Intrepid?


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.

How do i change the spark plugs on a 2003 kia rio


INSPECTION

1. Disconnect high-tension code from spark plug.
2. Remove the spark plug.
3. Connect the spark plug to a high tension code.
4. Hold the spark plug with insulated pliers 5~10mm from a ground.
5. Crank the engine and verify that there is a strong blue spark.
If there is no spark, inspect the following points.

Step Inspection Action

1 Check for good connection of ignition coil Yes Go to next stop.
No Repair or replace
2 Check if resistance of high-tension leads are OK Yes Go to next step.
No Replace
3 Check if the ignition coil is electrically charged
1) Ignition switch "ON"
2) Check if the engine coil (+) is electrically charged
Yes Go to next step
No Check the wire harness between ignition switch ignition coil and ECM
4 Check if resistance of ignition coil is OK
Resistance
Primary : 0.36~0.44Ω (at 68°F (20°C))
Secondary : 10.9~13.3kΩ (at 68°F (20°C)) Yes Go to next step
No Replace
5 Check if ECM is OK Yes
No Replace

REMOVAL

Do not attempt any maintenance on spark plug if engine is hot.
1. Disconnect negative battery terminal.
2. Carefully remove high-tension leads.
3. Use compressed air to blow any dirt or debris from around spark plug hole.
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.

Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug.

INSTALLATION

1. Install spark plug into cylinder head.

Tightening torque : 18~22lb-ft (25~30N·m, 2.5~3.0kg-m)

2. Reconnect high-tension leads.
3. Reconnect negative battery cable.

I need to know the timing sequence for a 1998 Mercury Mystique 2 liter


ignition timing or valve timing?

ignition timing not setable.

info:
The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

Change spark plugs


My 2004 Verona had factory installed "NGK BKUR6ETB" regular spark plugs which I replaced at 30,000 miles. The 2005 model year is supposed to have Iridium spark plugs. To replace the spark plugs: 1. Remove plastic top engine cover. 5 nuts 10mm socket. 2. Unplug connector from each ignition coil. qty 6. 3. remove 2 hold down bolts per ignition coil. 10mm socket. 4. remove ignition coil, lifting straight up. 5. Spark plug is now accessible, use deep well 5/8 spark plug socket to remove.
