Sounds like y'all are picking up your power at the wrong place. You don't want to use the "Start" circuit at all. Use the "ON" side of the Ing. switch, and from there to both switches. From both switches to the pump. Actually, it only takes one wire on either leg. From the Ing. switch "ON" to the momentary button, with a jumper to the toggle switch. That supplies power to both. Out of the push button to the "OUT' side of the Toggle and then to the pump. This way it will only work with the ing. switch ON, and using either button or toggle will send current ONLY to the pump as the other switch is not used and leaves an open in the circuit. Turn your Ing. switch on, push the button until it stops "ticking" and then start. If the mechanical pump quits, flip the toggle, and use the Elec. Pump to get ya home. And when you turn off the Ing. switch, the pump's off even it you forget to switch the toggle off. Hope that's clear without a diagram.

I think I'll just stick with one switch controlling the pump, either the starter solenoid or the separate pushbutton, but not both.
