Is it flashing green to red, or is it just solid?

That means its charging but not discharging the coil to make the spark. It should be cycling about 10 times a second. Use the same LED test light to test the PIP sensor by connecting it to the first pin on your ICM (should be gray/white wire) and see if that flashes.

If it’s 10 times per second the camera may not have been able to catch it, I’ll review the video and see. If it doesn’t flash I will do the test again while I’m testing voltage there, and have someone crank it while I look. I didn’t have a 2nd person when I did the test the first time.
I did also see it can be the ignition switch. Which my truck did keep cranking after I took the key out for 5-8 seconds

It went green to red, then it stayed red. Flashed a few times but battery needed to be charged at the time

Yep. I got that part. But a normal incandescent light should be flashing like a strobe... I don't know how your led light behaves... It might have a filter in it to slow down the light from pulsing fast.... I dunno.

True, didn’t think of that. I’ll be testing the ignition switch tomorrow, I’ll update when I do that. I’ll also have the test light ready to test the relay if it does decide to crank by itself again.
