    Yeah, ensure you're clicking "Save" and cycling the ignition key off & back on.

    This is what I sent to the ECU. Cycled key off/on, synced again (pulling from ECU), and checking that it was the same:

    Just to be sure of something, change the Output Setup to "DIS Waste Fire" (Cam Sensor - Not Used), and see if it starts.
    If not, I refer you back to post #10. Is the Actual System Pressure and Rated Injector Pressure really 58 psi?

    Yes, GM crank trigger wheel. All of these are GM parts, but I don't understand what you are asking when you say "is the cam sync timed for 24 crank...".
    But yes, in the Ignition Parameters (when the cam sensor is used), it's a 1x cam and 24x crank. I changed when I bought the motor was the cam.

    I don't have a pic on my computer, but here is my cam gear - http://ls1tech.com/forums/17557292-post434.html

    So it didn't run on "DIS Waste Fire" (Cam Sensor - Not Used)? Ensure the battery is fully charged before starting the engine.

    I'll do that now. Injectors are stock LS3, 42 lbs (well, 41.74 or something) @ 58 psi. I just readjusted that. System pressure is 55-58ish. Changed to Waste Fire and Cam Sensor - Not Used.

    The battery isn't dropping below 11V at its lowest, then it pops back up to at least 11.8 almost immediately. If that is enough to make this EFI system not work then I'm selling it tomorrow. No sense in putting myself in a position to be stranded every time I listen to the radio with the engine off for more than 5 minutes. I don't get the feeling that is the issue here, but the battery is on the charger as we speak.

    I didn't say that was the problem...I just want to avoid running it low with all these start attempts.
    I really need to know if it starts on "DIS Waste Fire" (Cam Sensor - Not Used)? Yes or no?

    Oh, I wasn't suggesting you were, just sort of thinking out loud. I'm willing to try anything, and you know more about this than I do.
    No, it did not start on waste fire cam sensor not used.

    It should have started. This means the crank sensor might not be transmitting the proper signal (or its wiring), or the 24x crank reluctor isn't installed onto the crankshaft correctly. You'll need to verify this by checking the Cranking Timing (Ignition Parameters) with a timing light.
