K20A3 reflash immobilizer problem

When I first got my ECU back, the key light kept flashing and the car had a hard time starting/sometimes wouldn't start. After pulling the - battery cable/fiddling with the green immobilizer plug a few times the problem stopped.

Then about three weeks later it came back. I did the same thing before and after messing with it for 15-20mins the problem went away.

I know this sounds like a bad wire or something, but the problem wasn't there before I took off the immobilizer and sent it in. And I was very gentle when taking it off/unplugging it/reinstalling it etc...

Is this a problem you have encountered before? Could it be Hondata error?

Help! My honda doesn't feel as reliable as before!

You may have damaged the Immobilizer or it may have heen damaged in shipping. If that is the case you may need to get a new immobilizer and have it matched to your key and ecu.
