I bought a 95 eprom ecu on ebay then plugged it up to my car and it didn't start. I cranked it for like 30 seconds. I then took my stock 97 ECU then plugged it back up and it started right up. Shouldn't this be plug and play? I think I bought a broken ECU. Can someone help me confirm this. Did I do something wrong? The connections only go in one way.
