The ECM, according to the manufactures sticker (also indicated are the timing procedures) states the ECM# is E5AE-9C485-CRD. Can that number be interchanged with other ECM numbers? If so, anyone know what compatible numbers might be?

That's not an ECM #. The catalog says that's a Calibration Rework Kit, as shown below. You can see what ECM #'s look like in this post: https://www.ford-trucks.com/forums/1...l#post16390352. And if you can find that number or the calibration code, which also shows in that thread, I can find the ECM #. The calibration code is discussed two posts after the one in the link.
But I had an Ah Ha moment. Appears the internal fuel pump isn't getting any juice. I hooked up my voltmeter and there's no current running to the pump. Guess I have some work to do finding the right wires and going to their source. Suggestions will help. Thanks!!
I'm older than dirt, so excuse my reminiscing about the old days when Microsoft was a start up in Bill Gates garage. If only I had bought stock.....
Hey, I remember that same era (although I learned that Bill Gates merely purchased DOS from somebody else and had no real garage-type of R&D efforts like Jobs & Woz did) and don't consider myself older than dirt, it's all in your mind!

I thought it was beautiful and aligns with what I have learned over the years... thank you for the help, reps for that.

Thanks, Gary. I'll do my best with what you provided. External fuel pump (on the rail) is working. I could not hear the internal pump. As I have a wooden bed, I pulled a few panels, took the cover off the tank and listened again. Nothing. So I tested for power in the connector. Nothing.
As best I can tell, I need to check the yellow wire for power and trace it to it's source. Has to be a break in there somewhere.
On Page 103 for a single tank I see a pink/black wire for power to the in-tank pump. And on Page 104 for dual tanks I see an brown/white wire as power to the rear in-tank pump. The yellow wire is the sending unit signal to the gauge.
I'm didn't see the black/pink wire to the connector. But I'll check again. Possibly it's just really dirty and a cleaning might reveal the correct colors.
Hi Vince - No, once it is warmed up I hear the fuel pump for a second or two and it shuts off. Starts right up!
Wow, once the engine compartment is warmed up, you don't have this issue, very strange. Well if the engine compartment is warmed up, then it may be dried up too. I would also be looking for water running down a wire into a connector, relay socket, etc.
Any water on the drivers side floor on rainy days?
What would happen if this truck were garaged on a rainy day?
Anyway, pretty easy to pull your computer, pop the covers, check it for water stains, and get the ID # off of it.
Thinking out loud; So, for the first 3 minutes or so, the computer runs off programming that ignores most sensor input until the ECT temp sensor is warm. No change to the fuel pump logic if it's a cold start or warm start.
The Internal fuel pump is not getting power. Therefore the external fuel pump is overloaded as it is drawing all fuel by itself, which may explain why it has to run for a long time until there's enough fuel in the rail. But if it's actually on a timer, then that doesn't make any sense. Or does it?
I wouldn't spend any time figuring out the reasons why. Since you know the in-tank pump isn't getting power then I would figure out why and fix it. And since the high-pressure pump has power then it has to be something to do with the pink/black wire. Or, you have power but no ground.
In any event, fix that problem and see what happens.
As stated above the clock in the computer must run for the fuel pump to stop after one second and the fuel injectors to start firing.
No clock then the fuel pump runs and the fuel injectors do not fire.
Starting up when the fuel pumps stop running is the clue here.
Change the computer.
