Will it run if you spray carb cleaner or a little gas down the intake? What is your fuel pressure?
Also, test your tps voltage to make sure it is not putting it in "clear flood" mode.
Stop throwing parts at it. It has to be methodically troubleshooted. Let's give it a try. Does your check engine light come on when the key is turned to the "on" position? Look at a couple of fuses, ECM/BAT fuse 15A,--- ECM B 10A--- ECM 1 10A
They all supply the ECM with power.
