    Default Terminator/HP No Start Issue

    Daily driver 442 clone, 350 Olds, TH400, Terminator TB, flashed ECU to HP (latest), FAST Dual Sync distributor, MSD 6AL (digital), @ 30K miles since install.
    Over the last couple weeks, car would randomly 'turn off', no rhyme or reason, as in as if the ignition switch were turned off. Reviewed all wiring, connectors, etc, as well as replaced the module in FAST dual sync distributor, plus the coil, spark plugs, and checked all spark plug wires. Sometimes it would start right back up, other times would take a few minutes of waiting, then fire. The random intervals became closer together in time, and finally, would not restart. At this point it primes, cranks, initially fires, and immediately refuses to run/fire. I obviously suspect a sensor out of range, but have never troubleshooted one of these systems at this level, and was hoping for some pointers? Can any provide general troubleshooting steps to get me going in the right direction?

    Thank you Danny. I have that link noted/saved, have reviewed it several times, and have removed power from the ECU overnight as a start. Raining here today, will get back on this tomorrow. Also reviewed a troubleshooting video on YouTube, and will most likely enable datalogging.

    If the Data Monitor doesn't display legitimate cranking RPM, troubleshoot the distributor.
    See the "Ignition Signal Flow Chart" on Figure 11, Page 20 of the Holley EFI Wiring Manual:

    That was my first thought, the distributor, but I went through it, it's right. I replaced the module anyway, and it does the same thing. Thinking maybe the MSD box, but those are usually go-no-go. Had the ECU disconnected from power overnight, no help. Going to flash it and try again, but it's raining like mad, probably through tomorrow. I'll get to it shortly though. I'll make sure to follow up on the post too. As always, thank you very much Danny, appreciate all you do! -Mike

    When it doesn't start, does the Data Monitor display legitimate cranking RPM or not? Look at the Data Monitor on the 3.5" LCD Touchscreen.

    When I tried to start it after the power removed for some time, I didn't have my laptop hooked up. It was raining so hard I didn't want to run out there with it. When the flatbed dropped it off at my house the garage was blocked, so he left it on the street. I will drill down on this over the weekend and get good info to provide.

    OK, datalog & System Log. Looks like it's starving on startup. Unless I'm not reading it correctly? Maybe a bad WBO2 sensor?

    You should've uploaded the actual datalog & System Log file, not a picture. However, if 82 RPM is your cranking RPM, that's not fast enough.

    Oh I see, no, that 82 is just where the line is on the graph, must have clicked in the graph area. It's a point in time value. The actual logs, figured they were too big, and when I try to attach I get an invalid file error. But on cranking it's like 450+, it even fires here & there, but never actually starts.
