You should check for diagnostic code to see it you can get a lead on where the fault lies. Depending on how you check for a spark on TC motors, you may not get a spark and lead you to wrong conclusions. You must leave all spark plugs in place and use a known good or new plug in the leads to check for spark. Harley motors 2001 and later use compression detection to fire spark plugs. No compression means no spark. If you still have no spark on one cylinder, (the motor should fire up and run on the other cylinder -fact-) then it may be the ECM or wiring from ECM to coil. Did you check the HT lead? It will NOT be the crank position sensor as this supplies both cylinders.

Well if your coil pack blew while engine was running than it probably shorted out your ecm..take it off and look at the plastic. If any looks distorted like from heat than its probably bad, also you should check the stator output first. On all three sides..one side can be bad. Of course im talking from experience from working on import bikes.. being you have a twin each side is separate. Meaning each side has its own electrical components. Including ecm..It should have at least two plugs going into it..one for each side of motor...hope I helped good luck..

No spark to front coil pack



Judging by your question you have automotive experience though for safety sake I will have to state some precautions anyhow. With the engine running and in park with the emergency brake set. Check your working coil packs "hot" wire with a multi meter. Set to 12 volts and check amperage and volts delivered. I would recomend checking each of the working cylinders if possible to establish base line readings. If you are receiving similar readings on the down cylinder then you have a short in the coil pack and it will need replaced. If you are not receiving a similar voltage and amperage you likely have a short and should trace the feed wire for that coil. As with all repairs if you are not absolutely sure of your capabilities to fix the problem you should seek the help of a professional. Happy motoring.

How to change Spark Plugs in a 2007 Toyota Rav-4 with a 3.5 V-6 engine


1. Check the gap at the base of the new spark plugs with a spark plug gap tool. If the gap on any plug is not between 0.039 and 0.043, exchange the plug for a new one. Do not attempt to adjust the gap on the plugs.
2. Open the two latches on the passenger's side of the air-filter box. Pull the front half of the air box toward the front of the engine and push it to the side. Remove the air filter from inside the air-filter box. This allows you access to the ignition coil packs.
3. Unplug the wiring harness from the top of one coil pack. Remove the bolt securing the coil pack with a ratchet and socket, and pull the coil up from the engine.
4. Remove the spark plug using a ratchet, 6-inch extension and a spark plug socket.
5. Hand-tighten the new spark plug into the RAV4's engine and torque it to 14 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket.
6. Squeeze a small amount of dielectric grease into the rubber boot at the bottom of the ignition coil pack. Push the coil pack onto the new spark plug until it clicks into place. Tighten the coil pack bolt to 6 to 7 foot-pounds with a torque wrench, 6-inch extension and a spark plug socket. Reconnect the wiring harness on the top of the coil pack.
7. Replace all four spark plugs, by repeating Steps 4 through 7 on all four plugs.
8. Sit the air filter back into the air-filter box. Reinstall the front half of the air-filter box and close the latches to lock it in place.


good luck

Where do the spark plug and wires go on my 1999 nissan maxima


The Spark Plugs are located under the Coil Pack in the Cylinder Head. You need to remove the silver cover on the front part of the engine which are held down by Allen Bolts to access the Coil Pack. You will need to remove the two bolts holding the Coil Pack to the Cylinder Head. Pull up on the Coil to remove the Coil and inside the hole will be the Spark Plug. The rear part of the engine next to the firewall has no cover so you will need to just remove the Coil Pack. The Nissan Maxima is very picky about the brand of Spark Plugs you replace them with, You should only use NGK Platinum Plugs or Better in your Maxima, Any other brand will make your car run rough.

Replace spark plugs 2004 dodge intrepid

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.

Where is the coil pack located under the hood


Follow the spark plug wires away from the spark plugs. The coil packs are on top of the ignition module. The coil packs have two terminals each and will have two spark plug wires attached to each coil pack. There are 3 coil packs and I would recommend replacing all three at once. They are bolted down to the ignition module bracket with a total of 6 small screws. Two per coil pack. Remove the small screws and the electrical connectors and the plug wires. Dont forget to mark the wires so you can replace them as you found them. Installation is just the opposite of removal.

Location of sparks plugs


For Jeep Cherokees with a 4.0 engine; (if you are standing in front of the vehicle looking back at the engine compartment) the spark plugs are on the left side / the same side as your battery. What look like spark plugs on the right side of the engine are actually your fuel injectors. On the exact opposite side of the engine block, all 6 spark plugs are held in place with a long rectangular box (called a coil pack) that has 3 small raised boxes on it. The coil pack is the length of the engine block and about 1 1/2 wide. There are 4 large approx 1/2 bolts that hold this coil pack in place. There is a plug on the back end / closest to the fire wall where you can upplug this coil pack but I couldn't unplug it.
Simply, remove the 4 bolts holding the coil pack in place, lift the coil pack away from the engine block and the spark plugs are exposed. The boots that attach to the spark plugs are "fixed" in to the coil pack. Replace your spark plugs some type of using anti-sieze compound, adjust your gap, and torque to 19 lbs. NOTE: use dielectric grease on plug boots and coil pack ends of wires. can also be used on plug in bulbs.
The above answer is great but if they are platnum plugs dont bother setting gap because you usually don't get a spec anyways and you do more harm than good. The gap is preset.
