Is the security light flashing? I recall something about needing to do a case relearn or something to that effect when switching motors. Believe it had to do with the ECU not being linked to the new motor or something to that effect.
Do you have the ECU that goes with the new motor on hand? If you do try that, if not you gotta do a case relearn or something like that. I have no idea how to do that one.
