A low amp draw should not kill a PCM/ECM the most it will do is cause it to reset. To call a ECM you really need to overamp/overvoltage it.

so would say a dying battery cause the ECM to reset? i have heard on more than 1 occassion that ecm reset could cause engine stutter on startup (my original symptoms) when it tries to “re-learn”. Maybe that was the cause of my problem all along?

Incidentally, dealer says he gave me a new battery because mine “was on the bench” so much this week. Aside from the new ECM, and reflash unit, ($1000+ in parts) he throws in a new battery? I am always dubious when someone gives me something for free, there must be more to the story.

How do you overamp/overvoltage?
