Unsure if spark plug wires are connected to the coils correctly

Replaced a bad ignition coil, and now I'm unsure if the wires are connected to the right terminals. I can hear a spark sound when I turn the car on.

I presume what you replaced was the coil pack. if it's a six cyclinder which my windstar was... the numbering on the pack is one to three on one side. and 4-6-5 on the other. either ford had a better idea or they wanted to see if mechanic paid attention. you haven't mentioned the motor is running rough, but the spark sound suggests something is off. start from the coil pack and make sure each wire is where it should be. it's numbered right on the pack. the wires hopefully will have numbers stamped right on them.
follow each wire to see which cyclinder it goes to to make sure the order is correct.

What should the resistance be on a coil pack 06 Xterra?


My info says you don't have a coil pack. You have coil on plug ignition, one coil for each spark plug. If you have a misfire on a particular cylinder, your trouble code should tell you which cylinder, then you check fuel--spark--compression on that cylinder. A p0300 misfire code is a misfire common to all cylinders, or the computer thinks there is a misfire but can't tell which cylinder.

Misfired cylinder 6, replaced coil, plug Misfired cylinder 5, replaced coil, plug Misfired unsure which yet, all of these happening within a week. It will run fine for a day or so after rep


change all plugs with proper ones - they are picky for some reason - do not change number or brand from original - coils were probably ok, - get some injector cleaner and run through it but check for exhaust leak at e g r tube - is a common over looked cause of misfire - a thing to keep in mind is misfire isn't always spark issue. hope I was of some help

I need to replace a coil pack on my 2000 Olds Silhouette. I know I have to rotate the engine. But am unsure on how to do it correctly.


you do not have to rotate the engine to change the coil packs. just turn the van off and unplug the coil pack un bolt it and pull the spark plug wires off

There is a misfire in my engine, changed plugs & wires. now it reads that the fuel leveling sensor is bad, will this help?


If there is a misfire, the cylinder that it is misfiring in will be recorded as a code in the computer.

Have the car scanned to determine which cylinder is bad. Then, replace the coil pack going to that cylinder.

According to the obd code i am getting a misfire in the number one cyln and it kind of sputters what is causing it


1. Bad or fouled Spark Plug at #1 Cylinder.
2. Bad or misfiring Wire going from the #1 on the Distributor/Electronic Ignition Coil to the #1 Cylinder.
3. Misfiring at the #1 on the Distributor/Electronic Iginition Coil.

a. Unplug the #1 Wire at the #1 on the Distributor/Electronic Ignition Coil.
b. Using an Auto electrical testing: Probe, wire and ground clip electrical, stick the Probe into the opening at the #1 Distributor/Electronic Ignition Coil. Use the grounding clip - clipped to a portion on the engine.
c. Start the Vehicle and check for rhythmic spark.
d. If there is NOT rhythmic spark, the Distributor/Electronic Ignition Coil needs to be replaced.
e. Turn off the engine.
f. If there is rhythmic spark: Reconnect the #1 Wire at #1 on the Distrubutor/Electronic Igntion Coil.
g. Disconnect the #1 Wire from the #1 Spark Plug.
h. Again using an Auto electrical testing: Probe, wire and ground clip. Insert the Probe into the end of the #1 Wire and clip the ground clip onto the engine.
i. Start the engine again.
j. Again Check for rhythmic spark.
k. If there is NOT rhythmic spark the #1 Wire needs to be replaced. (Replace all Wires as a Set).
l. If there is rhythmic spark then the #1 Wire is fine.
m. Turn off the engine,
n. Remove and Inspect the #1 Spark Plug. Clean if necessary and Regap.
o. Reinstall the Spark Plug and reconnect the #1 Wire.
p. Restart the engine.
q, If the code reappears:
r. Replace all the Spark Plugs.
Let me know if this helped or if you have additional information or questions. Feel free to contact me at FixYa.Com.

How to check and fix a cylinder #1 firing problem. Cylinder, plug, or wiring?


You can test each spark plug, but disconnecting the wire as the engine is running. If it runs rougher, then that plug was good. If there's no change, then that plug may be bad. If it runs rougher, it could also mean the wire is bad.


To test the ignition coil (you may have one coil for each spark plug, or one for every two plugs, this part I am unsure of with your model) remove the wire from the plug and then remove the spark plug, then put the plug into the wire (DO THIS WITH THE CAR OFF). Start the car and while using INSULATED PLIERS touch the plug tip to a good ground spot such as the frame even the engine itself, but not to the battery. If there's a spark or crackling sound, then that coil is good.

You can test each wire by hooking it up to a voltmeter and setting the resistance to 20,000 OHM.
The reading will vary based on the length of wire. 12inch wire may register 6-7 while a 30inch wire may register 8-9. If it registers below 6 regardless of length, then the wire should be replaced.

1990 Subaru Legacy shorted out the ignition coil. I replaced it and in less than 1 mile,it shorted out the new one.


Subaru engines (including Legacy and engines of many other automobiles, GM, etc.) have returned to so-called wasted spark ignition systems since advent of the electronic distributor-less ignition (having been used historically in early engines with magneto ignitions). With this approach, the ignition systems are less expensive and usually quite reliable. At the same time, however, a shorted spark plug (cracked or carbon clogged, etc.) (or bad ignition spark plug wire) grounds both the ignition spark and the false spark being used. This means that it also grounds the corresponding respective ignition spark of the other 180 degree out of phase cylinder (that uses the same the same coil because the spark current is connected to the spark plugs of two cylinders). Since such a defect allows more current to flow in the spark coil to two plugs when the resistance of the spark plug gap disappears due to a cracked plug, etc, it seems likely to hasten coil burn out if the spark plug/plug wire defect is not corrected before installing the new spark coil.

To explain further, wasted spark means that when a cylinder is ready to fire, it gets a spark to its spark plug while part of the spark (from the same coil and current) as a sort of copy is also sent to another cyclinder at the same time but when the piston in that cylinder is exhausting its ignited gases 180 degrees out of phase from when its spark is needed. When the second cylinder is ready to fire and receives its "spark, the first cyclinder the also receivesa "wasted" spark "copy" of the one needed by the second cylinder. Economy is achieved in manufacture because otherwise electronics would have to turn on and off four different spark coils to distribute four different sparks as needed to the four cylinders. With wasted sparks (which are cheap), because the spark current of one coil is connected (internally in the ignition coil unit) to two cylinders that are in the same position but 180 degrees out of phase in firing, the system can turn on and off two spark coils twice as fast with half the electronics and fire two cylinders that are 180 degrees out of phase. A four cylinder engine thus uses only two coils, a six cylinder engine, three coils, etc., in a wasted spark system.
