Possibilities of no WTS?

What are the possibilities not not getting a WTS light?

Fuel heater is disconnected and good fuse, PCM is new, gem module is new.

My brothers truck just randomly shuts off. Then when trying to re start it has no WTS light. Sometimes we can flip the key a bunch of times and it will come on, and sometimes it sits for a few days before it decides to start. We pulled the engine bay harness apart and can't find any bad wires. The PCM has power and grounds where it should as well. Any ideas?

Next would be changing the fuse box out? He said it had a little corrosion when he changed the gem module.

No WTS light is no power to the PCM. Or a burnt WTS light bulb.
But I'd check all fuses with a test light, on both sides of the fuse. Also the PCM connection. Does he have a chip?

Yep there's a superchip in it. Bit it does it wether the chip is in or out. Next time it dies I'll check the fuses for power that should have it and maybe that will narrow it down to what circuit is bad.

Just talked to him and he said that everything that he can find that's supposed to have power does at the fuse box and at the PCM plug.

The WTS doesn't really indicate power only, it's more an indication that the PCM is "up & running" as it should. If the computer isn't running the way it's supposed to, it may not have gotten to the point where it checks the status of things to decide to illuminate the WTS light, how long, and weather the GP's need to be activated, and is stuck.

Think of it as a Blue screen of Death for the PCM sometimes. The problem might well be internal to the PCM if all else is what it should be....

That's my thinking too. But the thing is that it's a brand new PCM from ford and the truck is doing the same thing as with the old PCM.

He's ready to burn the truck already, but it's too damn nice I keep telling him. Lol

When it dies is it just a crank but no start situation?

The next thing to concentrate on, after all the power wiring has been confirmed (and it sounds like you've done that), would be to maybe carefully inspect all the Grounds. They are equally important!

Dies and cranks but will not fire. Acts like its not getting fuel. We added a bunch of grounds and checked what we could. We are going to tear into the interior wiring next.
