The engine is suddenly not cranking at all?

It sounds like the starter motor has gone bad, but to be sure we need to check for power at the starter solenoid trigger wire.

Here is the start motor location so you can check it out, and I have included a video that may help as well.

As said in my original post, it is nothing to do with the starter, battery, or alternator as those are all running perfectly. I did an engine scan on it, and it was reading as running but didn’t actually start. Found out later that I was the exhaust camshaft position sensor reading the signal wrong. But now I have a new problem; the car will start now but only 1/3 times perfectly, 1/3 times will crank for about 20 seconds and then run, and 1/3 time will just not crank at all. I did get 2 sensors and tried both to make sure the sensor wasn’t faulty. So now the problem is partially fixed, but I’m not sure if it’s still the same issue or if it’s something else.

Yep, sorry about that, so now you say sometimes the engine will not crank over at all and sometimes it will crank but not run, correct? Can you upload a video of what the engine is doing so I can see?
