No spark spark plug not firing lack of spark from ignition coil

If there is no spark coming from the coil on your 1987 Mazda B 2600 with a 2 barrel carburetor, there could be a few potential causes. Here are a few steps you can try to troubleshoot the issue:

1. Check the ignition control module: The ignition control module is responsible for generating the high voltage needed to create the spark in the ignition system. If the module is faulty, it can cause a lack of spark.
2. Check the spark plug wires: The spark plug wires carry the spark from the ignition system to the spark plugs. If the wires are damaged or not connected properly, it can cause a lack of spark.
3. Check the spark plugs: The spark plugs are responsible for creating the spark that ignites the fuel-air mixture in the engine. If the spark plugs are worn out or damaged, they may not be able to create a spark.
4. Check the ignition coil: The ignition coil is responsible for creating the high voltage needed to create the spark in the ignition system. If the coil is damaged or not functioning properly, it can cause a lack of spark.

If none of these steps help resolve the issue, it may be necessary to have the ignition system checked by a mechanic or repair shop. They can test the components of the ignition system and determine the cause of the lack of spark


It is possible that the black wire that is connected to the little black box on the side of your distributor could be causing the lack of spark in your ignition system if it is broken or not connected properly. The black wire likely carries a signal from the ignition control module to the ignition coil, and if it is not functioning properly, it could prevent the ignition coil from generating the high voltage needed to create a spark.
To troubleshoot this issue, you will need to repair or replace the broken wire and ensure that it is securely connected to the little black box on the side of the distributor. You should also check the connection between the little black box and the ignition control module to make sure it is secure and functioning properly. If the issue persists after repairing or replacing the wire and checking the connections, it may be necessary to have the ignition system checked by a mechanic or repair shop to determine the cause of the lack of spark.

Have you checked the wiring, the spark @ plug, Power to the coil???

Ignition Coil Troubleshooting: (No) Fire in the Hole

www.secondchancegarage.com/public/coil-troubleshooting.cfm

Pull the spark plug of cylinder 2. Put the coil on the spark plug. Ground the sparkplug and have someone crank the engine. See if you see a spark. If you have no spark switch coils with another cylinder. If still no spark it could be one of the wires going to the ignition coil. If there is a spark do you smell gas at the spark plug hole? Could be no fuel to the cylinder.

need more info (need to know what type of ignition system your vehicle has: (1) traditional ignition coil /distributor system, or (2) electronic ignition, but lack of spark problems are usually a faulty coil
on traditional vehicles, and on the newer electronic ignition cars, total lack of spark would be
a faulty ECM (electronic control module) - partial lack of spark (diagnosed with a HEI (high energy ignition) spark tester kit), would be caused by a faulty coil pack (in the waste spark system), where
there's 1 coil pack for every 2 spark plugs.
I bought my HEI igntion testere kit for $20, but Harbor Freight sells a similar unit for $10.
Hope this helps.

Distributorless Ignition System General Information This vehicle uses two different types of ignition systems. The 3.7L, 4.7L, and 5.7L engines do not use a conventional distributor. The 5.9L engine uses a conventional distributor. The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Procedures in this section are for the 3.7L, 4.7L, and 5.7L engines; please see the section on Distributor Ignition Systems for procedures for the 5.9L engine.
Distributorless ignition systems (EI) are used on many current engines. This system uses the waste spark method for distributing secondary voltage. In a waste spark system, an individual coil is used to fire one pair of engine cylinders simultaneously. These cylinders are known as companions, since each of their pistons is at TDC at the same time. On a typical V6 engine for example, cylinder 1 is at TDC compression while cylinder 4 is at TDC exhaust. This is also true of cylinders 2 and 5 as well as cylinder 3 and 6.
The cylinder on the compression stroke is known as the event cylinder, while the cylinder on the exhaust stroke is called the waste cylinder. Since secondary resistance is very low in the cylinder on the exhaust stroke, little voltage is required to fire the plug. For this reason, the majority of available voltage is consumed by the cylinder on the compression stroke.
One spark plug is attached to each end of the secondary coil winding via the spark plug wires. This series circuit arrangement causes one of the plugs to fire in a forward direction (center electrode to outer electrode), and the other spark plug to fire in a reverse direction (outer electrode to center electrode). The firing voltage requirements on the waste spark ignition are significantly greater than a traditional ignition system primarily because it takes 30% more energy to fire a plug reverse polarity. When a spark plug is fired backwards, it fires from the outer electrode to the center electrode. This is a high resistance path since the electrons do not flow as easily from a cold, dull surface such as the outer electrode to a hot, sharp surface like the center electrode.
Since the coil and plugs are arranged in a series circuit, a typical plug gap of .050" results in a total gap of .100" for the whole circuit that includes two spark plugs for the companion cylinders. The waste spark can overcome this added resistance by producing high secondary output voltages due to low resistance in the primary winding. Another reason higher secondary ignition voltage is required is cylinder pressure; specifically, the lack of it. Generally, event cylinders require 10 to 12-kV to initiate current flow across the spark plug gap, while only 2 - 3-kV is needed to fire the waste cylinder. Therefore, the air gap in the waste cylinder creates no more resistance than the rotor gap does in a conventional ignition system.
There are two different methods used for coil trigger. One method sends the crankshaft sensor signal directly to the ignition module to activate the coils, while the other sends the crankshaft sensor signal to the PCM and the PCM controls ignition operation either directly or through a separate ignition module.
Waste spark ignition advantages

• It has fewer components than conventional distributor-type ignition systems.
• No mechanical adjustments to set ignition timing.
• No mechanical load (turning the distributor shaft).
• No unwanted timing variations caused by gear lash or other worn distributor components.

Another advantage of waste spark is longer coil life. To illustrate this point, consider a six-cylinder engine with conventional ignition. At 3000 RPM, the coil must fire 9000 times per minute. This is calculated by dividing the engine speed by 2, since the cam turns at half crank speed, and then multiplying the distributor RPM by the total number of engine cylinders.
In contrast, the coils on a six-cylinder engine with waste spark only work a third as hard. This is because there's a coil for every two cylinders and each coil fires every crankshaft revolution. This means that at 3000 RPM, the coils only fire 3000 times per minute. This allows each coil to operate with less dwell (time that the coil is energized), resulting in less heat buildup and longer life.
Coil Over Plug System The coil over plug system was developed so that spark and spark timing could be better controlled on an individual cylinder basis. Each cylinder has an ignition coil mounted directly above the spark plug on the cylinder head cover. A short suppresser/connector replaces the spark plug wire and links the coil to the plug. There are different methods used for primary triggering. Some manufacturers use a combination coil/module, which means each coil has its own control circuit that is activated by the PCM. Others use remote mounted modules to trigger the coils.
Each individual coil is allowed to saturate while all other cylinders fire. For a V-8 engine, this allows a period of seven firing events for coil saturation, compared to three events for the same V-8 engine with a waste spark system. The coil over plug system also benefits from a minimum amount of energy lost, due to the resistance of spark plug wires.
Coil Near Plug System The coil near plug system also features multiple ignition coils. An ignition coil/module is mounted in proximity of each cylinder. There is a short length of spark plug wire between the coil and the spark plug.
Each ignition coil/module has its own control circuit and is activated sequentially by the PCM. All timing decisions are made by the PCM. This includes both ignition timing and duration of the spark.

the ignition coil changes low voltage from the battery (12 volts) to high voltage (about 50,000 volts) to fire the spark plugs and ignite the fuel in the engine cylinders and drive the piston down

Too many choices. Try spraying starting fluid into air intake in order to determine if it is lack of fuel.
If that does not fire at all, then attach a spare spark plug to one of the spark plug wires, with the spark plug thread grounded. Then watch for spark when cranked.
If not, then consider if ignition switch is getting current to ignition module, by using a 12 volt test light. Take ignition module/coil to place like Autozone for testing. Last I can think of is distributer module. Can also be tested if you take it in, but watch carefully when you take it out, so that you can put it back in with the same rotation. Use tape to make a mark.

1. Note: Electronic Ignition engine timing is entirely controlled by the PCM. Electronic Ignition engine timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings.
   

The CKP sensor is used to indicate crankshaft position and speed by sensing a missing tooth on a pulse wheel mounted to the crankshaft. The CMP sensor is used by the COP Integrated EI System to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.

1. The PCM uses the CKP signal to calculate a spark target and then fires the coil pack(s) to that target shown in Figure 51. The PCM uses the CMP sensor not shown in Figure 51 on COP Integrated EI Systems to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.

1. The coils and coil packs receive their signal from the PCM to fire at a calculated spark target. Each coil within the pack fires two spark plugs at the same time. The plugs are paired so that as one fires during the compression stroke the other fires during the exhaust stroke. The next time the coil is fired the situation is reversed. The COP system fires only one spark plug per coil and only on the compression stroke.
   
   The PCM acts as an electronic switch to ground in the coil primary circuit. When the switch is closed, battery positive voltage (B+) applied to the coil primary circuit builds a magnetic field around the primary coil. When the switch opens, the power is interrupted and the primary field collapses inducing the high voltage in the secondary coil windings and the spark plug is fired. A kickback voltage spike occurs when the primary field collapses. The PCM uses this voltage spike to generate an Ignition Diagnostic Monitor (IDM) signal. IDM communicates information by pulsewidth modulation in the PCM.

1. The PCM processes the CKP signal and uses it to drive the tachometer as the Clean Tach Out (CTO) signal.

The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by a pulse former within the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition timing is determined by the powertrain control module in response to engine operating conditions based on stored data tables or maps. Once ignition timing has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 5, cylinders 4 and 3 and cylinders 2 and 6) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This ensures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

Integrated Electronic Ignition System The Integrated Electronic Ignition (EI) System consists of a crankshaft position (CKP) sensor, coil pack(s), connecting wiring, and PCM. The Coil On Plug (COP) Integrated EI System uses a separate coil for each spark plug and each coil is mounted directly onto the plug. The COP Integrated EI System eliminates the need for spark plug wires but does require input from the camshaft position (CMP) sensor.

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.
