Hondata

@spunkster do you have any other suggestions on things you recommend trying?

We swapped in a new fuel pump, checked all engine bay grounds, I pulled the day and visually inspected all wiring, we did a vigorous shake test, nothing yet.

I am not sure who socketed the ECU, I purchased the motor and ecu second-hand. I will try to find out. The s300 was provisioned, or licensed(can't remember which) by Rich tuned in Washington.

I am not sure if J12 is cut, I will look tonight and post pictures of the soldering done to the bottom of ...
