You only need to replace the housing if it's been damaged or in some other undesirable way altered. Code 31 is purely electrical. Do you happen to have any aftermarket fuel controllers installed? If so you may need to power them up before the ECU gets power... if not, pickup your TSRM and diagnose per the info in the book.
