I am pleased that you are trying to help me, so please do not think that I am being short with you, I am not meaning to sound that way.
************ No problem, I didn't take it that way at all. I have become used to working with dealer service personnel who have become frustrated when working on a problem, and most of my success came from a fresh set of eyes, a systematic approach to problem-solving, keeping in mind that an engine needs air, fuel, and a source of ignition to run, remembering that E = I x R, and that there are very few one-of-a kindd problems on Toyotas.

Yes I have checked for voltage at the fuel pump while cranking, I am not even getting the initial voltage at the pump when I first turn the key to Accessories.
************ There should not be any voltage at the fuel pump when you turn the ignition switch to accessory or to the on position. The only time there should be voltage at the fuel pump is when the engine is cranking or running.

The check engine light never comes on, under any conditions. It used to when I turned the key to on without the engine running
You mentioned the EFI relay and fuse, I have checked those and they are good. I do feel that the ECM must have a power source that has a fuse or something in it that is bad, because the likely hood of putting two ECM's in with the identical problem are slim.
*********** The EFI main relay and fuse supply power to the ECM. With the ignition in the on position, make sure that both the supply and load terminals of the EFI fuse have 12 volts.
With the ignition in the on position, make sure that the control side of the EFI main relay socket in the junction box has 12 volts.

The factory wire harness is not cut, it is perfectly intact.
I did find the exposed wire, and have corrected it. But as you can see, I am way passed being concerned about that wire, I have removed the radio from the car.
************* That is excellent news. I have seen people cut wire harnesses, and a problem almost always crops up some time.

Ironically, my dad is coming to visit, and he has a 97 Toyota Corolla. What we plan on doing is swapping relays from his to mine until it hopefully starts. His an automatic, so swapping the ECM if we were to get that far is out of the question. But the relays should all be the same.
I will keep you posted,

*********** OEM relays should have a part number screened somewhere on the relay case. Make sure part numbers match before swapping. Some relays in your car have the same part number, so you can also swap relays from your own car.
Good luck!
