Every ECM I get is sabotaged
What it’s like to get bullied by rich ********
Only Wires Connected to ECM, all test good according to FSM and don’t have voltage drop:
-Self Shuttoff
-IGNSW
-VB
-CRTN
-Back Up Power Supply
-Engine harness ground screws
-Throttle Motor Relay Negative (ignsw is powered from this relay at the moment)
-OBD2 K Line
All Connectors on the ECM harness are unplugged. It is only being supplied its power and tested for output over the Kline pin. Nothing else is connected.
K Line drops to ~6.5v once engine ground screws are connected.
Replaced engine harness, ignition switch, sourced computers from the junkyard and from eBay. Same result
