ICP leaks and no starts can be a huge pain for 6.0L owners. From a truck that never starts to hot no starts to lower performance at high throttle input due to lower than desired icp. In this video I show the basics of ICP leak testing on a truck that will not start hot or cold and how it is supposed to sound when doing the air test so you can pinpoint the location of the leak. I am sure that I will have a Hot no start video in the future but for now this one just had a bad IPR and never built any pressure. By following this method I was able to pinpoint and replace the right faulty component the first time and you will too, saving money by fixing only what needs fixing.
