I have a zzr600 in the garage that I am fixing to sell. It ran a few months ago, but I took off carbs and cleaned them along with replacing fuel filter. Now the fuel pump does not work. It works when putting voltage right to it, but not detecting any voltage at plug. I see not cut wires, it is in neutral. It should prime as soon as I turn key on like my zx6r. What could stop voltage from going to pump? Also bought new fuel pump relay to no avail.
