If they are Bennett tabs, there should be an orange wire feeding the switch assembly. On this wire there is a black fuse holder. Check for a blown fuse and/or corrosion. Also check the harness plug at the pump. If nothing (pump or solenoids) works it's power or ground. You can jump the motor with 12 volts to test as well as the solenoids. You don't have an oil leak do you?
