Charging issues

[MTF]

Corrosion and/or loose nuts at the starter terminals is a common problem.
Disconnect the battery and then unbolt the nuts and clean all the eye end terminals.
Maybe use some dialytic grease.

Checked the nuts and none are loose, but they’re all oily. Assume that’s probably not the best for them, so tomorrow that’s what I’ll do along with checking what PCM is commanding

Have you unplugged the three PCM connections and checked for corrosion?

There was a thread on the F-150 forum with a guy similar problem.
He ended up putting a new ignition cylinder in. As soon as he did that his fuse 27 blew.
He seemed to think the fuse was the intermittent problem, not the ignition cylinder.
You might want to look at both as a possible problem.

I have a relocated fuse 27 already. I did have the truck just click one time when I tried to start it, but I just cleaned the terminal and it fired right up.

I had a similar issue that ended up corrosion on the bottom side of my main fuse box.

Got it finally right and sold it. Just grounds all corroded around.
