The ECU can go bad and still run. It happens all the time. After you verify your firing order, grab a replacemnent ECU and toss it in. See if that makes a difference. It might, and it might not. Then, run a good ground from the ECU and try it again. These trucks are notorious for lousy grounding circuits, and I have jumper wires actually running to the negative side of the battery!
And, I hate to say this, just because the engine is fresh doesn't neccessarily mean that it's any good. Have you done a compression test to verify your rings and valves are working properly?
Hang in there, don't get discouraged! We'll get you going!
