Alright, so the ECM is throwing a P1516 code, which is IMRC input error. The car has no beans whatsoever to boot. if I leave the engine running, and cycle the IMRCs by hand, the HP comes back instantly. Once I shut the car off and restart it, no power again. The car has a newer IMRC controller, installed about 25K ago. Any ideas? This is pissin' me off.
