Why is there no spark in my ignition coil?
Note: If all of the ignition coils aren’t delivering spark, the issue is likely with the control side (primary side) of the ignition system, rather than a single ignition coil. An absence of spark from just ONE ignition coil points to a bad coil.
How to test a coil pack or ignition coil?
1. How to Test an Ignition Coil on a Modern Car: 6 Different Methods 1.1. Perform a Visual Inspection 1.2. Swap the Suspect Ignition Coil to Another Cylinder 1.3. Use a Spark Tester 1.4. Use a Coil-on-Plug (COP) Probe 1.5. Check the Resistance of the Ignition Coil 1.6. Monitor the Ignition Pattern with an Oscilloscope 2.
Can a spark tester jump the plug gap?
The issue is, it takes less voltage to fire a spark plug that has been removed from the engine than one that’s still installed. So, although you may have spark, it may not be adequate to jump the plug gap with the engine running. A quality spark tester, on the other hand, requires tens of thousands of volts to fire.
What was the ignition module on a 1993 GMC k1500?
1993 GMC K1500, K2500, K3500 Pick Up. All of the information you need to diagnose a no-start problem caused by the ignition module, or the ignition coil, or the distributor pickup coil. Wiring diagram. Component pin outs.
How to troubleshoot a GM 4.3L no start?
Check that the 8 cylinders are getting spark with a spark tester. The distributor cap is good. The ignition coil is good. The ignition control module is good. The crankshaft position sensor is good. The distributor cap could be bad. The ignition coil to distributor cap high tension wire could be bad. The ignition coil could be bad.
What makes the ignition coil start to spark?
Also, after receiving the pick up coil signal, the ignition control module starts to switch the primary current (of the ignition coil) On and Off. As you might already know, it’s this ‘Switching Signal’ that makes the ignition coil start sparking away.
What happens if there is no spark in the ignition?
The ignition system is the one responsible for creating and delivering spark. Without spark, the engine will Crank but Not Start. The ignition system of the GM vehicles covered by this article use a distributor type system. Distributor cap. Crank sensor. Ignition module. Ignition coil. All of the above ignition system components can be tested. 2.)
Can you use spark tester instead of Coil on plug?
Do not use a regular spark plug instead of a spark tester to test for spark. Do not remove the ignition coil from the spark plug while the engine is cranking to test for spark. This method for testing for spark can ruin the ignition coil, and now you have another problem to worry about.
Why does my Nissan Altima have no spark?
I am now pushing a 2005 Altima with 2.5l because it will spin over but fails to start. No codes show on my snap-on scanner. It has no spark, the tack does not move. We changed the crank sensor, and no change. My scanner said that it should have 5 vdc on one pin of the connector and that the sensor should ohm out at 165 to 200 ohms.
What does a Nissan Altima ignition coil do?
The Nissan Altima/Sentra’s ignition coil is a three wire Coil-On-Plug ignition coil. Which means that each ignition coil has a transistor inside that plays the role of an ignition control module (ICM). Below are the circuit descriptions of each wire (circuit): Circuit labeled 1 :
How does the Nissan Maxima ignition coil work?
The Nissan Maxima ignition coil is able to power the spark plugs because of an electrical process involving the primary and secondary windings and a change in the magnetic field that occurs between them. As time goes on, however, the connections in the coil break down, due to the constant exposure to currents of high-voltage.
Note: If all of the ignition coils aren’t delivering spark, the issue is likely with the control side (primary side) of the ignition system, rather than a single ignition coil. An absence of spark from just ONE ignition coil points to a bad coil.

Why does my Nissan club have no spark?
It has no spark, the tack does not move. We changed the crank sensor, and no change. My scanner said that it should have 5 vdc on one pin of the connector and that the sensor should ohm out at 165 to 200 ohms. When I tested the plug I had 12 vdc and the sensor reads open across all the pins. Did you rebuild the motor? did it die when driving.
