Any ideas on what would cause

If there were burn marks on your hood and air filter and no wire around it I'd check the ground for your cab. Under the passenger floor panel grounded to the frame on my early 99

Negative ghost-rider...

The distribution box I was suggesting you check the PCM relay in has a connection on the front where it is fed across the engine over the cowl all the way from the starter solenoid on the passenger's side fender via a fusable link.

Sounds like the plastic cover has been removed from this terminal (bolt with ring terminal and nut powering your junction box) the terminal will be exposed. That's constant hot.

The wire mesh on your filter (I'm assuming Donaldson/Tymar style) has contacted that terminal and is completing the circuit to ground through your HOOD!

GET THE PLASTIC SNAP ON COVER BACK ON THAT DISTRIBUTION BOX BEFORE YOU BURN THE TRUCK DOWN!

You were hitting bumps, grounding out the entire distribution box power feed and shutting the PCM down when the voltage dropped below it's lower limit.


It is not uncommon for the black snap on piece to disappear for whatever reason, leaving this main power feed exposed. It snaps on and keeps this terminal covered and safe. Without it, your metal filter overmesh is going to burn the truck down. Luckily it didn't set its own paper on fire. Must be fire retardant.


On Edit:

This is the cover you're likely missing, or it's been pushed to the up position, uncovering the terminal:

Directly behind that plastic cover is a terminal that WILL contact that filter screen that is always hot. No bueno.

That's it. I had it ground out while removing the filter one time so I put electrical tape on it. Never had the cover to know it was missing where can I get one? Also anyone know where I can get a metal tube for my air intake?

Bump. Someone help me find this part before my truck catches on fire.

Sunrise Ford or Autofair Ford (Sponsors) should be able to order it.

dont know the part, but as long as you can find some, super 33 or 37 electrical tape, its good for 600 volts per double layer. dont use the cheap chit, its junk... just wrap the hell out of it till you can find that part... any good hardware store with a electrical department should have that tape...
and leave your air filter open.. dont enclose it...

Any salvage yard should have one. Fuse box is a common part.

What is the actual part called?

 

[Charles]

Just wait till a guy that's a dick turns around and gank one off their truck like somebody did to you...

LOL


But seriously, hit a salvage yard and just grab one. Hell, I might have one rolling around in the barn.

If you have one that would be awesome. Because unless they interchange with some other models no salvage yard here would have one. Lucky if they have more than 5 pickups.

If I remember, I'll look. I guarantee you somebody's got one or 3 laying on the ground somewhere doing nothing.

I'd post a thread looking for one but I don't know what to call it haha.

I checked my spare engine harness, didn't have one or I'd have given it to you.

 

[ghohouston]

Just for future reference, and i.d.m. that water has penetrated can/ will cause the same issue. Luckily yours was an easy fix

 

[KYkickinit]

Bump. Someone please tell me they have one of these I've had no luck finding one.
