Button should be pushed in.
With a fresh filter, it's a good idea to cycle the pump...key on for a few seconds, then off, repeat a few times, then try starting. Also listen for the pump to cycle when you first turn the key on.
The terminal can be jumped, but I would try that after testing the voltage there by hooking up the multimeter leads, then turn the key on to see if there's power there...will only last a few seconds before going back to zero volts. If good, then jump the terminals on the wire and listen for the pump.
