Why is there no ignition spark? - BMW 7 Series 95-98

It sounds like there may be an issue with the ignition system specifically for the wok burner. Here are a few potential causes:

1. Faulty Ignition Head: The ignition head may not be generating enough spark to ignite the gas. Since you mentioned that a weak spark can be seen when foil is placed between the ignition head and earth, this could indicate a weak spark from the ignition head.
2. Dirty Ignition Head: If the ignition head is dirty or covered in grime, it may not be able to generate a strong spark. You can try cleaning the ignition head with a soft brush or a toothbrush to remove any debris or buildup.
3. Loose Connections: Check to make sure all the electrical connections for the ignition system are tight and secure. A loose connection could cause the ignition to fail.
4. Faulty Spark Module: The spark module provides power to the ignition system. If it's faulty, the ignition may not work properly. However, since the other burners are working fine, it's less likely that the spark module is the issue.

If none of these solutions work, it may be best to call a professional to diagnose and repair the issue.

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.

Here is a diagram showing the spark plug leads attached to a coil pack:

In this diagram, the ignition coil is at the center and is connected to the spark plug leads, which are in turn connected to the spark plugs. The spark plugs are located at the end of each spark plug lead and are responsible for igniting the fuel in the engine's cylinders.

In a typical engine, there will be one ignition coil for each cylinder, and the spark plugs will be connected to the ignition coils through the spark plug leads. The ignition coil generates a high voltage electrical current, which is transmitted through the spark plug leads to the spark plugs. The spark plugs then use this electrical current to create a spark, which ignites the fuel in the engine's cylinders and powers the vehicle.

Range: Gas burner won't spark or ignite A surface burner igniter switch and a spark module activate the spark electrode when a burner is turned to the "Lite" position on a gas range's cooktop. If the surface burner switch, spark module or wiring in that circuit fails, the spark electrode won't work, and as a result the gas burner won't light. If those components work but the electrode won't spark, the problem could be that the spark electrode is coated with spilled food of is bent or broken. In addition, the electrode won't spark or ignite the burner properly if the ceramic insulation sleeve below the tip of the electrode is cracked or broken. If the gas burner isn't lighting, these repairs may help.

Replace the spark igniter electrode

The spark igniter electrode-also called the surface burner igniter-is an insulated electrode that provides an ignition spark to light a surface gas burner. It sparks and makes a ticking sound when the burner switch is turned to the Lite position. Replace the spark ignition electrode if it fails to spark or if the ceramic insulation sleeve is cracked or chipped. How to Replace a Spark Igniter Electrode in a Gas Range Find This Part

Replace the surface spark module

The surface spark module is in the ignition circuit for the gas surface burners. When a surface burner control knob is turned to the "Lite" position, it provides voltage to the spark electrodes on the gas surface burners. If the surface spark module fails to provide the electrodes with voltage, then it should be replaced. Find This Part

Replace the spark igniter switch

The igniter switch is an electrical switch on the stem of the gas surface burner control valve. This switch completes a circuit to the surface burner spark module, causing the burner igniters to spark when the burner switch is turned to the Lite position. Replace the burner igniter switch if the burners don't spark when you turn the burner control knob to the Lite position or if igniters spark constantly even when the burner knobs are in the Off position.

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
This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems
Attach the clip to ground and crank the engine to check for spark
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
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.

Hello,
Is the igniter sparking? Some are battery powered-check the battery or replace it. If you have a standard push button piezzo igniter or a rotary style igniter, check for spark. Can you hear or see the spark? It's hard to see the spark in bright daylight. It's easier to view the spark at dusk or dawn. It should spark an "arc" at the burner. If not, adjust it if necessary. The igniter wire may have a short, causing the spark to arc somewhere else along the wire and not at the burner. Replace igniter wire. It's also possible the igniter tip where it sparks has a cracked or broken porcelain portion of the igniter, causing the spark to not arc at the tip where it's supposed to. Replace the igniter piece.

Hope this helps! Douglas

ignition timing or valve timing?

ignition timing not setable.

info:
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 the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle 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 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.
-----------------------------------------------------

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.
