Oil pressure sensor and ECM
Continuation of ECM repair and oil pressure sensor on 3126B. Recently had ECM repaired. Reinstalled and engine started, but I don't have oil pressure on gauge and low oil pressure light stays on. I've ordered a new oil press sensor however, after reading through my data download from the repair shop I see "Engine Oil Pressure Sensor" ---"NOT INSTALLED". Is there a possibility that the repair facility failed to put in "INSTALLED" ? Can this be rectified with the ECM installed or will I need to remove it again and return it to the repair facility? My thinking is, the new oil pressure sensor is not going to help.
Thanks in advance,
