212 F-150 -- No crank/ No start

[Angry Perch]

2012 F150 has had an intermittent no crank issue. New battery. Positive terminal was heavily corroded. Has been cleaned and new battery installed, but battery harness/ cable is on back order for a couple weeks. Was at Evergreen Ford and they didn't figure it out. Does not appear to be the Transmission Range Sensor (Neutral safety switch). Full power to everything, but nada when I turn the key. Let's hear your ideas.

Jackelope has probably blocked my number by now because I've been bugging him so much!

Muffler bearings?

Tried for 15 minutes a couple hours ago, and nothing. Just walked out to the parking garage, gave it a Fonzie punch on the hood, and it fired right up.

You should be good if you just never turn it off

It's got a big gas tank!

Getting a starter "click"?

No. Full power at dash, lights, etc. but nothing when I turn the key. Until I just randomly lay works, of course. Wondering if maybe something is heating up and has to cool down? I'm trying to keep track of all the details of timing to see if there is a pattern.

Can't imagine it's related, but the truck now always thinks I'm on a steep grade.

Based on this, I would bet that you have a lack of voltage issue. Low voltage at the right place will freak all sorts of systems out. I'd be checking voltage drops when trying to start.

Another place to check, sounds ridiculous,  but all those fords have a chip in the key, programmed to the computer, we see it at work a handful of times where something goes haywire with the key, the computer does not recognize it, and you'll get a no crank no start issue. With your dash illuminating and all systems working normally, minus no crank no start.


I'd be suspect of voltage though, it can cause a wide array of problems.


I would also be checking all of your grounds for corrosion/tightness.


Starter could be starting to go as well.


Corrosion is a big issue

To OP.  2013 F-150 here.  I recently had something very similar to you.  I have two vehicles, both experienced severe sulfating on the battery terminals this Spring.  Same thing happened.  I used a wire brush set on the cordless drill, and really scoured the inside of the terminal cables.  I haven't had a problem since.

I also filed the lead terminal posts.  Very carefully, did not breathe the lead dust.

Funny you mention the key. I had my wife bring her key to try. Nope. I also wonder about other things that might interrupt ignition. Alarm? The ignition itself?
