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:
- 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.
- 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.
- 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.
- 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.
I had the same problem. It used to vibrate alot when getting around 50 to 70 and then one time it cut of while i was driving but then the strangest thing happened and it turned back on and it was fine. But it did this a couple of times. Then the problem worsened and when i was at a dead stop say like a stop light or stop sign it completely shut off and couldnt get it started till about 30 minutes later. But it did that about 3 more times and then now i cant even get it started. So then i started to read the manual on my car and i checked certain systems and i would not get a spark. So I replaced the plugs, the spark plug wires, cap, rotor, ignition coil, battery, and now i took out the cpu and i was going to trace it back to whats faulty but yet my manual does not cover my version. So i tried looking on the internet for the chart to tell me what wires are what and there is none. And yes i checked the fuel system and fuel filter and it is working just fine. Please help me and im sorry for the long message i just wanted to let you know what all i have done.
You know for sure your getting fuel when this happens?
