I have finished performing the more advanced testing, continuity and resistance testing of all fuel injection related wiring. All results point towards a faulty ECM. I did notice that the engine bay was dirty when it left after the last ECM rebuild, and then when it came back for more diag into the selective ride system, the engine bay was very clean. water intrusion could be the culprit to the rapid ECM failure. Will post what the rebuilder finds.
