I have this same problem a 6 months a go
Problem was in soldering
Solder legs one by one that sort out my problem
Regarding your old Ecu do you have acces to tech 2 if yes just SPS and all will be fine

SPS= Service Programming System. Basically reflashing the ecu with new sw using TECH2 with SAAB TIS or nowadays TECH2 with TIS2Web. TIS and TIS2Web is GM technical database where you can get access to ecu flash and security/immo programmings.
