The trucks had a HPT ecu in it for around 100k miles, thought I?d run into town and put some diesel in the truck before barrowing it from a friend, stopped at the fuel pump, threw in a full tank, and then the ECU just stopped communicating. There is power to the ECM, but none after. HPtuners said get logs and data from it? that would be simple it if actually scanned. What are my options, and has anyone had this issue?

I?m worried about purchasing another Hptuners ecu just to run into the same issue again.
