Where are the spark plugs located in the crank sensor?
During engine cranking, only the Right side spark plugs (exhaust manifold side of the engine) are fired. Once the engine starts, the PCM now commands the ICM to fire both coil packs through the Dual Plug Inhibit (DPI) circuit (circuit 6 of the ICM Top Connector), . Each coil pack feeds spark to 4 spark plugs on either side of the engine.
What causes a spark plug to stop firing?
When the ECU does not analyze the information correctly, then it can cause certain cylinders to stop firing. Normally, these misfires occur at random with no set pattern. This is the best way to tell that the issue is occuring as a result of a faulty ECU rather than another component like the spark plugs.
How does the ignition module and crank sensor work?
The ignition module now starts to activate the coil packs. During engine cranking, only the Right side spark plugs (exhaust manifold side of the engine) are fired. Once the engine starts, the PCM now commands the ICM to fire both coil packs through the Dual Plug Inhibit (DPI) circuit (circuit 6 of the ICM Top Connector), .
Can a camshaft sensor cause a car not to have spark?
The advantages to such a system include the absence of a rotor or distributor cap, which may burn or crack with use, along with the absence of a vacuum advance diaphragm, which can rupture or leak. But when a camshaft position sensor takes the place of a distributor, failure of that sensor could result in there being no spark.
How does the electronic spark control system work?
There are three basic components of the Electronic Spark Control (ESC) system. The Electronic Spark Control (ESC) sensor detects the presence (or absence) and intensity of the detonation by the vibration characteristics of the engine. The output is an electrical signal that goes to the controller.

What should ignition timing be for electronic spark control?
Basic ignition timing is critical to the proper operation of the Electronic Spark Control (ESC) system. Always follow the Vehicle Emission Control Information (VECI) label procedures when adjusting ignition timing. Some engines will incorporate a magnetic timing probe hole for use with special electronic timing equipment.
