    After all this happened, I went to start the car to bleed the cooling system, and it will not start. I guess I'll just start from scratch and check everything.

    This could be a blessing in disguise. Now you might find the real problem. (A permanent failure is easier to find than a temporary failure.)

    So I found a bad wire to the power side of the ignition. Broken wire at terminal. Repaired connector, set TPS to .63V, and now engine will only run if the main & idle knobs are turned all the way rich. I will reset the TPS to a higher voltage to make it richer, but what would be a good starting point above .63V to try? I'm sure a small voltage adjustment will make a large adjustment? Thanks again for the help!

    Do you know about "the wire?" I'd have to look, I've forgotten. There's one wire in there you ground or switch to +12V. I forget, to change the map from larger to smaller engines.

    I do know about the wire. I reset the TPS sensor to .63V, and then set the idle screw, and started, the tune seems to be much better. I thought the .63V was when the engine is at idle, but I must have misunderstood.

    Yep, that's the ECU pink wire. Small block (ground) or big block (+12V) engine selection.

    Correct, it's idle position, not engine idling.
    Step 5 of Adjusting the TPS, states:
    "Turn the ignition key to the RUN position",
    and "Do not start the engine" in bold print.
