Im just trying to help.. with an idea that helped me. you guys challenged my theory..

Now that you have a parts car.. if you got the cts.. swap it. Dont bother taking yours out.. just take the parts car sensor and plug it into your cars harness and start the car. Try the fuel pump test conector and listen for the pump to come on..let us know if you hear it hum.. Then swap the mpi relay. Then maybe swap ecus if you can.
