Discover How To Test Your Entire Ignition System With One Simple Tool

  • Published on Dec 22, 2016
  • I show how to test your entire ignition system including the spark plugs, spark plug wires, ignition control module, and ignition coil. I use a multimeter, a 12-volt test light, and jumper cables to do all the testing. By checking your complete ignition system you will be able to pinpoint the problem and easily fix it.

    If you want to be able to check your entire ignition system here is a link to a multimeter reader.

    another test for the crankcase position sensor , is to watch the dashboard Tachometer while cranking, you should see a RPM reading, if you don't you probably have a bad CPS or bad wiring !

    Thanks so much - Easy to follow and understand, unlike some of the other videos.

    Sometime bad condenser and resistor can cause no start too. Some car might have it and some don't.

    That last test was a useless test. You were ohm testing a metal shield if you got through the corrosion you would have had zero ohms on both modules. All other test we're good but I think you misread your ohms reading on the coil.

    I just had my 89 s10 pickup inspected in the beginning of November. before I took the truck to get it repaired I replaced the gas tank fuel hanger and pump assembly. All brand new. Two weeks ago the truck died. When I turn the key on I can hear the pump run but it refuses to start. When I dump gas into the throttle body the truck starts right up and then stalls. When I run a test by placing a paper clip in the ALDL connecter and watch the flashes 12 and it continues to do this over and over. There's no other codes in between the code 12. This makes me think that it's missing the reference pulse and the ecm is not turning on the fuel pump and making the pulse width modulation zero. Couple years ago when I purchased the truck it did the same thing. It refused to start. When I went to replace the fuel pump i noticed entire hanger assembly and pump were new. What would cause a new pump to go bad? There's a problem but i don't know what is wrong.

      I will have to do some research for you.

    How did the testing procedures you did show what part failed that lead you to know it was crank sensor cause i also noticed you said you installed a new ignition control module so was it both the crank sensor and the ignition control module bad, I did the test on the voltimeter with the crank sensor wires and it did not change a bit on engine crank so Im trying to figure out if its the ignition module or crank sensor or both, I also did not get the test light reading on removing coil pac and cranking engine it also did nothing,ive already replaced plugs wires and both coil packs and crank sensor only thing left i can figure to do is change the ignition module any thoughts would be appreciated. Tks

      That is right.

      @oxmanagain Awesome thanks for replying, I watched were you said test the crank sensor plug i assume you just unplug it from the crank sensor to test it and then you said have someone crank engine while you prode both terminals with ACV turned on and you should see 200 millivolts typically and i assume when you did that test yours did not originally read anything and thats how you knew it was the crank sensor?

      I tested everything and that was the only thing that failed. That is how I knew it was the crank sensor. I changed the ICM, the spark plugs wires and plugs, the coils and the camshaft sensor. The only thing that was left was the crank sensor.

    If there are sparks in the spark plugs it means all other components are working and there is no need to test them?

    • Ray Milligan

      Yup , no need to go any further , the system is working the way it should !

    • oxmanagain

      That is correct.

    I had engine code p0342 and p0335. I changed the camshaft position sensor and the crankshaft position sensor twice with no luck. After watching the video I troubleshoot everything on this video, since my OB2 Scanner advices to check ignition system. My ignition control module was the problem, did not work. I'm so happy to have my truck back. Thanks

    Spark plugs may fire in the atmosphere just fine, but in the high compression atmosphere inside a cylinder it may not.
