Paulgw,
NCangler has it right. When the switch is in the "On" position, you should hear the pump running. If you have a multimeter or 12 volt test light you can run this down fairly easily. Just remove the panel that has the switches on it and check to see if you have power running to the switch. Jump the leads from the multimeter from one terminal to the other. No voltage, trace wires back to battery to find out why. If you hear the pump come on when you jump the terminals, it's a bad switch ( or one that's been tripped). If it shows voltage and you don't hear the pump, you know it's between there and the pump. Remove pump and rig wires directly to the battery and pump. No running...bad pump. If it runs, there's a break in the wires from the switch to the pump. You can pick up a cheap multimeter (around $12.00) at most hardware or auto parts store if you don't already have one.

I hope this helps...let us know how you make out.
