Re: Sick of this asd issue
The voltage regulator for the alternator sits inside the PCM. So if with the previous PCM the voltage was ok, but now with the new PCM the voltage is too high, there is obviously something wrong with the new PCM. Just try and disconnect the small connector on the alternator. It will remove the power to the field and the alternator will stop generating power. Does the engine now run fine?

Just saw your answer now. Pin 86 is no ground, but is the power feed side of the ASD relay. The ground side, which is switched via the PCM, is on pin 85.
As mentioned in earlier reply, there was something wrong with the switching of the ASD relay. You did put a new relay in, which didnīt help. So then you will have to measure the wiring for continuity. You never replied anymore with any results thereafter.
