Thanks for asking your question. I will try and help you out.
The ECM should have unswitched power on pins 52 and 53. Keyswitched power on pin 70. The grounds are pins 65 and 67.
If you have good power and grounds on these pins. You most likely have a failed ECM.
Please reply back if you need more help or have more questions. I am happy to assist.
