You can briefly ground the two injector wires going to the ECA to see if the bank of injectors fire.

When you turn the key to ON, do you get the 1-2 Fuel Pump Prime ?
You should run your KOEO Self-Test, see what your computer knows.
Pull out your ACT and check the tip on the sensor.

More on the truck, it is getting good power to the injectors. I temporary run a ground while someone else cranked, and it wanted to spit and sputter. I was going to look at the computer wiring, but ran out of time. I noticed there are two computer looking boxes down there. I assume it's the one that has the larger bolt in connector?

Did you pull your computer and check the capacitors ?
If you put a test light or meter on one of the injector connectors, you should be able to tell if the computer is firing them.
Have you run the KOER Self-Test ?

It's not going to hurt anything.
The automobile EFI was ahead of the Truck, so you might get a few codes that you would not with your truck computer.
