hello a while ago u guys helped my diagnose a faulty ecm, the circuit that goes from pin c16 was blown like you can see in the picture. i got it repared by a local ecu repair guy. now when i installed the ecm again and when connecting the batt neg side i heard that it blew again and it did when i checked.
the ecm diagram show that c16 should be batt voltage. It recieves batt voltage when measuring and it has no continuety with ground when i measure it. do you guys by any chance know why this happens?

because im really stuck with why my truck wont start.
