The WTS light not coming on is an indicator that the PCM is not communicating either because it's not getting juice or unfortunatly it's compromised. If you can pull codes I would give that a shot before the new PCM.

Your WTS light should come on every time no matter how briefly. Disconnect both neg terminals of the batts and disconnect the fuel heater at the rear of the fuel bowl. While you wait, remove your PCM and check to make sure there are no bent pins.

I don't know exactly what the dealer can do. If the board is fried, you will need a new PCM. Just for grins try replacing the #30 fuse it's the 30 amp fuse, I don't know the location, and unplug the fuel bowl heater. Then try to see if you get the WTS light.

I'm a total noob when it comes to psd's and ford trucks in general.
Where is the plug for the fuel heater located?
I will unplug the neg terminals for the night.
Also any tricks for removing the 10mm screw on the firewall side. That thing is impossible to remove

Thank you for the suggestion though. Might have to get a "new" pcm. I don't really see where I did any damage though.
Anyone have advice on how to get the screw on the firewall side off?

The trick to removing that 10MM screw is, 1/4" ratchet and alot of patience lol.

I think I used a 3/8" drive shorty ratchet wrench. Fortunately I've got small hands so I can get down in there. It's tight, no doubt, but you need to do it, so be prepared to "give of the flesh"...

Man I feel like I've given enough already.
Doesn't help that the truck is lifted and that the screw is in the absolute corner of the engine bay.
Well I bought another pcm and it should be here tomorrow. Hopefully I can get everything sorted out
Once again thank you for all of the help

I'm starting to feel sorry for you. Get a 2' ladder and use 1/4 inch drive stuff. If I can get mine out a younger fellow can damn sure do his. 3/8 inch drive is too clumsy to use in the cramped quarters you're working with.
