Ok, so I move the pump to use IGN1 as a relay trigger. It already won't run on the first detent, the one I was formerly calling ACC.

Are these the 4 positions?
Off - Run - Ign1/Run/ACC - (Start)

That doesn't seem to work, because the engine will shut off when the key is in the second detent, (1st click forward from off).

Is the 1st detent to simply unlock the steering column and does nothing electrically? ACC terminal on the block ONLY has power from the 2nd detent on, not the 1st.

Thanks!
