I think you've eliminated anything it could be, LOL. Just double check everything to make sure. Fuel, air, spark. Has to be one of those three. Good luck.

If that injector light harness showed they were good, don't think about spending that type of cash on a new ECU. I'm pretty sure it has to be something mechanical, maybe electrical, but not ECU.

From what I've been told the ECU's went up in price just a few months ago. I havn't heard of anyone getting one cheaper than the price I listed lately.

I'm going to perform a leak-down test today and if all looks well with that I'm taking it to Ford tomorrow to have them use their high-speed diagnostic software on it. Hopefully I figure it out quick as this is my DD right now....

Well, I'm not even going to do a leak-down test. I went home for lunch and tested the compression again and #5 is getting intermittent compression. It will read 140 PSI and then 0 PSI. Then 20 PSI and then 0 PSI. If I let it sit for a little bit I'm able to get 140 PSI on the first test and then it stays at 0 PSI on the next test. Something is wrong inside the cylinder. I'm thinking it's either a bad valve seat, bent valve, or a valve guide has come loose. Either way, I'm taking the truck to Rick and letting him and Matt diagnose what's wrong with it. Hopefully it's something that can be corrected without too much money being thrown at it. I'll keep my fingers crossed...
