Did you replace it or did a shop do it? Be sure the plug is on good. With the CPS and O2s disconnected you have eliminated the most common source of shorts that kill the ECM. Is it warranted?
The ECM (computer) needs battery voltage, ground, and ignition switch voltage to operate. You need the capacity to check all of these.
Check all fuses in the fuse box under the hood. Be sure the grounds on the block are good.
You'll need a wiring diagram to jump out the ASD relay, Do not try it unless you know exactly what you are doing. You said you replaced it, right?
