I still can't track down a part #. Sorry.

I would be careful throwing parts at this problem. Two opinions have been presented 1) the K40 - posted by folks here and 2) the ECU - posted on another forum. Which is correct? I don't know.

I have never had a failure of either of these components so I really can't comment on what symptoms will arise from a failure of either. I jumped on the thread primarily to inform that the modules can be disconnected and removed without harm.

I would first try to determine which pin is power from the K40 and see if power is getting to the ECU. If that can't be done I would enlist a shop on this one.
