Jeff,

I have the injectors wired = the same way as you describe. When the engine is running below the staging = point, if I turn off the power to the primary injectors and then quickly turn = on the cold switch, the engine continues to run just fine. I just have to remember to turn off the cold switch at nearly the same time as turning = the primary injector power back on or the engine will get twice the fuel it = should. It’s been awhile since I tested this, but I think things work the = same way with switching the secondary injector power. It also = didn’t matter if the engine was above the staging point, that is, it would = continue to run just fine.

I assume = what Bill and Ed mean here is: If you disable the primary injectors, the = secondary injectors (if enabled) will remain operable, even below the staging = point – they won’t be automatically turned on. This is not = actually mentioned in the manual, though does make sense.

I do = not have the DPDT switches but rather have separate PRI and SEC power = switches plus the Cold Start switch.

To test = the above feature (which I have not) I would have to first ensure that = the Cold Start switch is ON … right now if I disable the PRI-only below staging point, my engine quits.
