Automotive Ignition System

FOR IMMEDIATE RELEASE
Blue Springs, Missouri, United States of America (Free-Press-Release.com) February 8, 2012 -- Automotive Ignition systems can be very easy to diagnose and fix with a little simple information on how they operate. There a basicly two types of systems, the old points type distrubuter system used into the early 1970′s and slowly fazed out over the years, and distrubuless ignitions systems used on present cars.
The old points system worked by using a set of points that open and close to send a reference signal on when the coil should fire. The points were a wear item and went out all the time. The new distibluless system uses these simply parts to operate.

* Spark Plug
* Plug Wire
* Ignition Coil
* Cam/and or Crank sensor
* Ignition Module
* Engine Computer

In order to have spark the cam and or crank sensors will have to tell the Ignition Module where they are at in there revolution and then the Ignition Module will consult the ECM and adjust based on temp., load, and other info. The Ignition module will then tell the coil to fire and it fires to the spark plug thru the wire. If you have a misfire or won’t run when it warms up i would look at the ignition module. Alot of them can be checked at your local parts store. If you have a decent code scanner and can read live data you can look to see if you have a crank speed reading that will tell you if your crank sensor is working. Most ignition coils have two wires coming to them, a ground, and a signal pulse. You can use a simple test light to see if you have a pulse signal at your connector but don’t use a test light to see if you have your spark coming out of your high voltage. If you have pulse to your coil and no fire to your plug its either the wire or the coil.If you don’t have a pulse signal you would go backward to you your ignition module or crank sensor. A bad miss or bad stumble on acceleration could be a bad plug or coil. Always try the easy stuff first spark plugs can go bad inside and not work at all causing a big problem on a 4 cylinder car. The order above on the parts is usually the the likelihood of the parts going bad too, spark plug being the most common. I would start to check a car like this start and see if you have spark at the plug, if you don’t check the coil, if you don’t have pulse at the coil keep going backwards to the module then the sensors. If you have spark coming out of your plugs and the car still wont run its most likely a fuel issue.

Its a lot easier to treat the problem like a path its either one way or the other based on the info you collect on the way.
