fsm = real, factory service manual from GM'/GEO. not chiltons or Haynes junk books, (rags/door stops) real factor manual is nothing less than best.
it even shows ever inch of the harness, and each sub connector, there, very nice information to find wires not connectec, right.
The grounds really matter,, so the ECU can compute and not make errors.
in some cases we need to meter or scope all pins on the ecu to see why its going nuts.
im sure the ECU is ok. itself .
