Truck died going down the road. Got it to a shop. Getting code 1117 power loss with key on. I have continuity tested all wire and they all check out. Have visually traced all wires all look good. Replaced ecm and truck will run for a few seconds and die. I don't know what else to do please help.
The fuses in the battery box?? Changed them still same thing.
What is truck make and year?
2009 pete 386. All fuses replace. They think the ecm is bad again
Rawze,
I showed them the first link yesterday. Went through all those spots everything was good. So they bypassed everything and ran a power wire to the ecm. Same thing. This has a brand new ecm in it. We took an ecm off another truck they had in the yard and truck ran fine. So I guess I got a bad brand new ecm?? They are overnighting me a new ecm.
What are the chances I received an ecm that was bad.
The second link is what my first ecm was doing truck would run but if you tapped on the ecm it would kill the truck that's why we replaced the ecm in the first place.
