2004 chrysler van 3.8 motor replaced coil pack still doesnt fire number 4 cylinder


If the coil pack has a four wire connector, one wire is primary voltage, the other three wires are ground, one ground for each coil, one coil fires two spark plugs. If problem with coil or ground, you would lose spark for two spark plugs. Did you visually check for spark, everywhere? What about the spark plug wire or the spark plug, itself?

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

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.

I got code PO 305 on a 2002 Mercury Grand Marquis, what is the spark plug wire part called, is it #5 coil, and should I replace the coil and spark plug and what should the spark plug be gapped at? Thank...


I got code PO 305 on a 2002 Mercury Grand Marquis, what is the spark plug wire part called
This will have a direct coil over ignition with a coil over each spark plug. The coil is the electrical part over the spark plug. The coil also has a rubber part that is called the boot or spark plug boot. The boots can be purchased separately but the coils will come with new boots.

is it #5 coil,

Have you checked to see if there is any spark coming out of the number 5 coil?



and should I replace the coil and spark plug and what should the spark plug be gapped at?

When was the last time the spark plugs where changed? It may be due for all the spark plugs to be changed. The spark plug gap is usually listed on the emissions sticker under the hood. It should be .050 - .056 or very close to that.

There is a sound in the transmission when the car turns.


probably the CV on the axle. Much better than in transmission. Check boots on all 4 CV joints for tears Ithere is a CV on each end of both axles. If torn, replace axle.

How to replace 1997 buick inition coil


I just did one the other day. There are three coils. You can determine which one is bad by using the number one spark plug wire and an old spark plug. Put the spark plug in the wire ( while it is still in the coil) and ground the plug against the engine block. Make sure it is grounded solidly to metal or you could get a nasty shock. Have someone start the engine. Look at the spark. It should be fat and blue. Turn the engine off as soon as you have seen the quality of the spark. Pull one of the wires from each coil in sequence and move the number one wire to that coil. Proceed as above. The weak coil(s) will have intermittent spark, yellow spark or maybe none at all. Once you know which coil(s) are bad remove the two small screws at the ends of the coil. They hold the coil down. Pick the coil straight up, pulling the contacts out of the ignition module. Set the new coil in place and screw it down. Both towers spark every time the coil fires so reinstall the wires in either spot on a given coil. Good Luck

Where are the spark plugs in the 2006 ford expedition


The spark plugs are located below the 'coil pack' in a hollow tube in the head. You must remove the spark coil retaining screw to access the removal of the soark coil. The reoval with expose the spark plug at the bottom of the hollow tube in the head. The total spark coil is about 6-7" long and when it comes out that is when you will see the spark plug at the bottom of that tube. It sounds difficult to find but once you know it is easy. There is no coil wire(typical spark plug wire) attached to the spark coil. It is fed by a special connector on the side of the spark coil. Look on the side that has the least number of hoses and equipment in the way. Find the top of the spark coil (about 1-3/4-2" in dia) with a wire connected on the side. There is a single small metric bolt holding the spark coil in place. It will not come out until that screw is removed. I hope that this helps.

No spark to the coil


No spark to the coil or is it no spark from the coil? First verify that you have 12 volts to the coil when you turn ignition switch on if not you will never have spark from the coil going to the plugs. If you do have 12 volts to the coil and still no spark you have a bad coil. To see if the coil is firing, unplug a spark plug wire from it's plug and hold it to a chasis ground while attempting to start the vehicle. There should be a strong spark and popping sound. Remember to wear leather glove or thick work glove if holding the wire by hand to avoid shock. If there is a strong spark then coil is good.
