SOURCE: no spark out of coil have spark to primary side ol

First test the coils:-- Remove the large wire from the center of the coil by pulling it straight out of the coil. Remove the retaining nuts and all the wires attached to the side terminals on the coil as well.Place the test leads from the ohmmeter on the side terminals, one on each side. It does not matter which lead goes where in this case. Note the reading on the meter. This is the primary resistance, and it should read between .4 and 2 ohms on your Ford coil.Move the test lead from the negative post on the coil to the center terminal where the large wire was removed. Keep the other lead on the positive post of the coil. Note the resistance reading on the ohmmeter. Your coil should have a reading of between 6,000 and 15,000 ohms for your Ford.Replace the coil with a new one if the readings are outside either of these ranges, as that would indicate a defective coil. If the readings are within range, reinstall the wires and retaining nuts on the side posts, being sure that they go back on in the same position they were in before you removed them.If the coils checked ok, then it can be spark plug itself faulty,

  • Put spark tester on coil and see if it sparks or not.Or only sparks once when just ignition is turned on.If yes then spark plugs is not the problem ,then its problem with ignition module, but if ignition module is tested ok or already replaced, then its distributor problem. ----- Other than that check the TACH wire for gounding out someplace, this will also kill the spark. Both TACH wire and BATTery wire should have power when the key is in the run and start position.---------Disconnect ignition coil wire from distributor, and connect spark tester to coil wire and engine ground. Spark Tester Hook-Up for Run Circuits Check Spark should occur at tester, when lead is touched to battery positive terminal. Turn ignition switch to RUN position, and touch diagnostic adapter lead to positive battery terminal. Sparks should occur at tester gap each time lead touches battery terminal.--------- If not the problem is distributor.--------- Getting this possibilities checked will help.Thanks.Helpmech.

    SOURCE: 1990 holden nova slx no spark from primary side of new coil

    The primary side of an ignition coil is not intended to produce a spark and it isn't wise to try. A test lamp or voltmeter can be used to check for battery voltage on the +side and for continuity through the winding. If the winding has continuity and a voltage is present then current will flow if the contact points or the trigger (optical, hall effect or inductive) and amplifier is working correctly. A 1990 model probably uses a trigger and an ignition amplifier

    I have a 2000 vw beetle that starts sometimes and no power to spark plugs when car turns over but wont start


    You need to diagnose whether the failure is happening on the primary or secondary side of the ignition coil.
    For the primary side: verify that there is battery voltage being supplied to the ignition coil all throughout the times that it wont start, or as you said "no power to the spark plugs". If you still have primary voltage supplied to the coil, then you look at the secondary. This is more complicated because of more parts involved. There is a secondary wire windings inside the coil, plus the plug wires and the plugs, and then there is the controller for the primary-to turn the primary on and off at the proper time for spark to occur. This controller is usually called the ICM (ignition control module), or "igniter" as in Japanese cars, or Power Transistor some call it, or some just have the engine computer directly control the coil primary. Finally there are engine sensors that inform the computer or ecm when to initiate spark-this is the function of the crankshaft position sensor and the cam position sensor. All these things have to work together for spark at the spark plugs. I hope this gives you a general guideline of how to diagnose your intermittent no start problem. First determine if it is a primary or secondary coil problem.

    Not getting a spark out of the coil?


    The proper procedure is to first check that the coil is getting power to the positive side of the coil with key in on. It must show power.

    If the coil has power to it, then check if the controlling device is turning the primary to the coil off and on-this is what the Ignition control module (ICM) does. Or in some cases a "power transistor" is used to control the coil primary (some imports, for instance).

    The ecu signals the ICM (or the power transistor) when it wants the coil to deliver a secondary surge through the coil leading to a spark. The ecu (or pcm) must get a signal from the crank position sensor so it knows when to time the spark.
    So if no spark, check if coil primary has power, then check secondary coil operation-if no secondary (no spark), possibly bad coil, bad ICM, or missing the crank position sensor signal.

    2005 dodge grand caravan 3.8L code p2305 ignition coil b secondary circuit. has no spark on 2 of 6 cylinders. I have replaced the coil spark plug wires and spark plugs. found some broken wires for the...


    Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.

    First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
    If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)

    So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
    There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
    The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.

    Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.

    No fire out of coil ! ,changed coil, new battery , battery line seems to give off weak spark.still no spark out of coil 73 vette with points distributer


    Very likely the points are bad.

    if you have replaced the points and capacitor and the coil, then the only other components are the wires and the resistor.

    It is simple to troubleshoot if you have a volt meter.

    With the ignition on, there should be 12 volts across the primary side of the coil (the small connections).

    Do not attempt to measure the secondary side of the coil (the big connection on the top) it will blow out your meter.

    If there is no voltage on the primary side of the coil, it is a bad resistor or a broken wire.

    We replaced coil with new one....no spark coming from coil


    Check if there is any power going to the primary winding of the coil. There should be roughly 12 volts on side of the primary. If there is none check for a blown fuse.

    There is no spark at the plug when pulled from the engine and engine is cranked.


    If there is spark with a jumper battery connected, you need a new battery. If no spark with a jumper battery connected, you need a new ignition module.

    No ignition to spark plugs


    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

    Primary circuit. Is the Spark Plug Wire.
    Secondary circuit. Is the Electrical connector on the Ignition Coil.

    Check the condition of the Spark plug, Spark plug Wires. and ignition coil. and the ignition coil Electrical connector.
