There is no flashing the old ecms. Disconnecting the battery does nothing.

Did you try the tap test I suggested

There is no checks you can do for the ecm without removing it and sending it out to be checked.

OBD1 was not that smart. It only coded when there was a hard failure. Codes do not always tell you the failure even on newer cars. You still need to do good old fashion diagnostics.

You do the checks I suggested to you. Based on those results, we determine if it is an ecm failure.
