All, Just circling back to let you all know and those who may see this in the future that it was a bad rotor cap and rotor. Replaced them with AC Delco parts for 45$ and she’s up and running. The leads were pretty corroded and I guess finally gave up.

I have a 2006 4.3 V6 Silverado 1500 WT that as of yesterday will not start. The last time I drove the truck was about a week ago before I parked it at the house. Luckily, its in my driveway so I can work on it. I'm a little confused though on why its not starting. I have tested the fuel rail pressure and have 59lbs when the fuel pump is engaged and about 59-61lbs when I try to crank the engine. I've tested the spark on all 6 cylinders with an inline spark tester and have posted the video of the number 3 cylinder's test below. They all managed to light the plug up telling me I have some spark, but i dont know how much spark at the plugs. I then checked the high tension line by trying to get it to arc off a ground bolt. It was sending power as i managed to shock myself through rubber handle channel locks, but it wasnt creating a visable arc. I also pulled a few plugs and they all were dry but had a color to them as if they were burning normally. I also tried shooting some starting fluid directly into the throttle body during crank; that didnt give me anything either. I'm thinking I have a spark issue; but am confused as I have spark at the plugs. Perhaps its not enough? My battery is dead now from troubleshooting so i'll be waiting for a charger to come in tomorrow. Until then - any suggestions???
