Alright. So I think I FINALLY got somewhere. From what I tested it's got to be the ECU as the culprit. Here's what I did.
I tested all grounds and they tested good, I tested the 2 power wires, 1 received 12v, and the black wire with red stripe didn't. However once I jumped the ASD relay it received power. Once I did this the coil also got 12V so I know the ASD relay and wires are all good. The ECU gets power and ground going into it, but it's not sending anything back, so the ECU has gotta be toast.

Before I got and fork over $200 to Satan, can anyone think how it could be anything else but the ecu? I've got power and ground going into it, and no signals at all coming out of it. NO check engine light, the ASD relay will not come on unless jumped, and same for the fuel pump relay. Thanks for the help so far!
