You need a multimeter.

1) Unplug ECU connector C and check for a short to ground at pin C3 (Red/Blu wire).
2) Also test for continuity between pin and the wired pin of the knock sensor connector.

 

done all of that already and put 3 different sensors don't k want els to do is my engine screwed

 

Post the multimeter readings obtained from the tests,
