Specifically, v this indict I"m gonna" assist you diagnose two of the most common failures with this type of ignition regulate module (ICM) setup:No start as result of a no spark condition either since the:Crank sensor has failed.ORThe ignition module has failed.Misfire due to a poor ignition module.
Since the ICM isn"t cheap and replacing the crank sensor is labor extensive (you"ve acquired to remove the time belt), testing the ICM and also crank sensor, on her 2.3L Ford Ranger or Mustang (or B2300), becomes a must!

What Tools perform I need to Test The Ignition control Module Or The Crank Sensor?
I deserve to tell you best off the bat the the one point you don"t need is a scan tool. You require a few basic things and also they are:MultimeterA digital or analog multimeter will certainly work.Wire Piercing Probe
You"ll additionally need an easy hand devices to remove the ignition module (if that tests negative that is), favor a ratchet wrench, sockets, etc.
Ignition Module Circuit Descriptions
The ignition regulate module has actually two connectors. Looking under at the ignition module (with the ignition module tho bolted to the intake manifold), you"ll an alert that the ignition regulate module has actually a top connector and also a bottom connector.
In the pin the end charts listed below is a short job description of what each wire does.
NOTE: although I"ve contained the shade of the wires, in the charts below, there"s a an excellent chance that these colors won"t match what"s top top your details Ford Ranger or Mustang or Mazda B2300. This is no cause for concern since the wires" job description doesn"t change.

How The Ignition control Module Works
The ignition module is tasked through activating the 2 ignition coil packs the feed the 8 spark plugs the the 2.3L 4 cylinder engine is fitted with.
Now, ns won"t enter minute technological detail as to how every little thing works in this ignition system. Simply the basics that you and also I need to get to the bottom that the problem. In a nutshell, this is what happens as soon as you turn On the vital and crank the engine:The crank sensor is fed with power and Ground.The crank sensor is a Hall-Effect form sensor.The crankshaft rotation cause the crank sensor come start creating two different crank signals.One crank signal is called the CKP (crankshaft position) signal.The CKP signal is just sent to the ICM.The various other crank signal is dubbed the CDI (Cylinder Identification) signal.The CID (Cylinder Identification) signal is the one the helps the ignition control module synchronize the ignition coil packs so that they fire in the exactly firing order.Both the ICM and the PCM obtain the CID signal.The ignition module now starts to activate the coil packs.During engine cranking, only the appropriate side spark plugs (exhaust manifold side of the engine) room fired.Once the engine starts, the PCM now regulates the ICM come fire both coil packs through the twin Plug Inhibit (DPI) circuit (circuit 6 of the ICM optimal Connector), .Each coil load feeds spark to 4 spark plugs top top either next of the engine.Spark Plugs on the input manifold next of the engine are described as: Intake side Spark Plugs or Right side Spark Plugs.Spark Plugs top top the exhaust manifold side of the engine are referred to as: Exhaust next Spark Plugs or Left side Spark Plugs.
