No start situation, or intermittent start, not firing ignition or fuel injectors properly. before it would start and die over 15 - 30 seconds, then sometimes it would just start firing the fuel injectors with the ignition on and engine off. I got some serious gremlins going on. I sent you my logs a year or so ago and you thought the ecu was defective but I shipped it to you and you said it was fine. My guess is intermittent voltage to some part of the ignition circuit, causing the initial fuel pump and injector prime to keep repeating or sometimes no power at all and occasionally enough power to actually start.
