What makes a GM ignition coil spark away?
This Triggering Signal is known as the IC (Ignition Control) Signal in the GM service literature. The ignition control module now starts to open and close the primary current circuit of the ignition coil and as you may already be aware, it’s this opening and closing action that makes the ignition coil spark away.

Why does my 93 Sierra have no spark?
You can’t post conmments that contain an email address. Fuel, Spark, crank – no start I have a 93 Sierra White, was running when parked. Picked up another Sierra that was missing under load, was swapping parts found 3 cracked plugs, and bad wires and the fuel pump vapor locking.

Why is my Vortec 5.7 not sparking?
Went and stuck it back together it, new cap new rotor wires will crank, spark and fuel but can’t get it to start. Triple checked firing order, can see gas in the throttle body am stumped. Any ideas of what this problem could be?
Why does my car have no spark when I start it?
As a result, This occurs after the ignition coil or module gets too hot. Furthermore, it could correct itself after the engine module cools. In some cases, a bad ignition coil will result in the vehicle not starting it all. A Bad Rotor Or Distributor Cap (cracks or carbon tracks that are allowing the spark to short to ground).
What to do if your ignition coil is not working?
Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor. The ignition module uses the information to time spark generation. Test these components if the energized coil fails to function.
Where does the spark come from in a car?
The spark created by the ignition coil is fed to the distributor cap by a high tension wire and from there to each engine cylinder by a spark plug wire.
What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits.

Where is the spark in an ignition system?
Electronic ignition pickups are a component found on traditional electronic distributor ignition systems. They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation of the distributor and triggers the ignition system.
