7.3 hard start or even no start due to no pressure, leaky o-rings, bad hpop pump or bad IPR Valve?

With this video I show how a failed injector seal caused a no start hot, long crank. I did do the dual icp test. They were within.1 of a volt at all times. That normal variance between sensors. It fooled me and caused me to replace or warranty out a pump that I did a few months back. I also tried a known good ipr valve and jumped the ipr valve. I was stumped because the dual icp test passed. I removed the valve covers out of desperation and stumbled across the obvious cause.
