Is the only way to test it is to disconnect inlet to tb and turn the key and see if it flows good?

there's a test valve on the fuel rail, and a test gauge plugs into it to test fuel pressure.

Should be electric, I think fuel injected is always electic.
Not sure but I think it about 35lbs, not sure. Do you hear the pump start up when
you turn the key to on, 1 click?
