Intermittent AEM ECU Offline
Okay, I'm having a problem that seems to be getting worse. Sometimes, when I go to start my car, the ECU does not turn on. I first thought is it was my MPI Relay but after 3 of those I've decided something else is the problem. After looking at the Wiring diagram of how the ECU is powered by the car I think my problem may lie in the transistors within the ECU which control the MPI relay to send power to the ECU. Anybody else seen this problem? Also, at times I can hear the Relay click rapidly for a while, sometimes not stopping until I shut the key off. Even when the Relay clicks properly, the ECU still does not power up. Just looking for some guidance trying to rule out vehicle wiring from internal ECU. Car has AEM EMS btw.
