The coil has two seperate circuits 1) primary (is this where you are checking?) the thin wires at the base of the coil. and a secondary circuit this is your high voltage side the spark side and it needs the primary side to turn on and off in order to work youe test light should flash on the negative side on the primary circuit if it does not you will not have spark and your triggering device is deffective if it does flash then you have an open coil and it should be replaced.
Hope this helps you

SOURCE: how can you test the spark plug coils, what is the

Dear Pablo,
You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.

No spark to my plugs on a 91 toyota corolla


Sorry, cannot assist, no knowledge of spark plugs!
By the way I was happy with the helpful replies I received when my 1999 Corolla 160i GLE had problems...it was correctly diagnosed as cv joints by several responses. This is a great service to people like me, so thank you 'fixya' :-)

96 nissan altima gxe runs good until it gets hot then stalls


I've been there.... A nightmare!!!

Your prolem sounds as the classical Hot Coil problem with no solution. Next time when engine stalls, check for spark, touch the coil and the ignition module. If they feel hot to the touch (can't hold it), chances are there is too much resistance in the High Tension side of the ignintion circuit.
This means the circuit from the coil to the spark plugs has too much resistance. Since you already changed everything I have to ask a question: Is everything as original specs??

When I had this problem it resulted that the gap between the terminals of the distributor cap (new) and rotor where to big, This created great resistance which heated the coil and quit sending spark.

Perhaps there is something in the High Tension circuit which is out of original specs. Is the gap in spark plugs correct?
Try an old distibutor cap. Do the metal contacts in the spark plug cables touch the metal of the spark plug contact?
Does the metal contact from the cable touch the metal from the coil's contact? Are they dry?

Check things which can create a gap where electriciy has to "jump" to complete its way to the spark plug. These are the ones which cause the hot coil and hot module trouble.

Anyone have the firing order diagram for a 2011 dodge nitro 4.0 liter v6? Also how do I get to the spark plugs on the drivers side? I can't figure it out!!!


Here ya go
Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug See: Ignition Coil\Service and Repair\Ignition Coil - Removal

  1. Remove necessary air filter tubing at throttle body.
  2. Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
  3. Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
  4. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil O-ring and replace as necessary.
  5. Inspect spark plug condition

Inspection

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.

Check for spark. Maybe a crankshaft position sensor is bad or a module.

Secondary Spark Test This spark tester looks just like a spark plug, attach the clip to ground and crank the engine to check for spark 91052p10.jpg
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems 91052p11.jpg
Attach the clip to ground and crank the engine to check for spark 91052p12.jpg
This spark tester is the easiest to use just place it on a plug wire and the spark voltage is detected and the bulb on the top will flash with each pulse 91052p10.jpg
The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available. The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse. The Air Gap type must be adjusted to the individual spark plug gap specified for the engine. The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump to. The last two types of testers allows the user to not only detect the presence of spark, but also the intensity (orange/yellow is weak, blue is strong).
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform diagnosis of the ignition system using individual component diagnosis procedures.

Ignition Coil Testing
  1. Remove suspect coil.
  2. Disable fuel pump by disconnecting inertia switch electrical connector.
  3. Reconnect the ignition coil electrical connector to the coil.
  4. Install spark tester 303-D307 (D81P-6666-A) or the equivalent.
  5. Crank engine while observing the tester.
  6. If a blue-white spark is not observed replace coil.

What is the firing order for a 2005 nissan titan crew cab? Which one is cylinder one and where can I find it? PLEASE HELP!!!


The firing order is 1-8-7-3-6-5-4-2 and the #1 cylinder is located at the left front of the engine and the spark plug and ignition coil for the #1 cylinder will be the first ignition coil and spark plug on the front of the left side of the engine on top of the valve cover, and to remove an ignition coil dis-connect the wire connector to the ignition coil, then remove the bolt securing the ignition coil (usually this is one 10 mm bolt) and give the ignition coil a twist as you pull it straight up and out of the spark plug well, and if you are removing the spark plug then use a socket with an extension and swivel to loosen up and tighten the spark plug, but use about a 6 inch length of 3/8 inch fuel line pushed onto the spark plug to actually remove the old spark plug and also to start the new spark plug down inside of the spark plug well to reduce the possibility of cross-threading or damaging the threads for the spark plug. Here are some images to assist you and the ignition coil location image shows the right side of the engine for reference, with cylinders 2-4-6-8 and this was just the best image that I could find to make that diagram, however they are laid out the same on the left side of the engine 1-3-5-7, and let me know if you require any further assistance.

No start on old gasoline forklift engine.


most likely the ign switch is ok if you are getting spark. so you have a hot spark at coil and weak fire at plugs? if you have a test light check the positive side of coil for power when turning key on and cranking. if it is dropping power on positive side then ign switch could be bad. can "hotwire" coil by jumping a wire to positive side of coil to pos of battery this will eliminate ign switch.
