if its injection it should be returning all the time. just put 12v on the fuel pump. do you know how many bar the fuel pump produces? i would guess the regulator on the fuel rail is either 2.5 or 3 bar
by pass is fine. i capped mine off but not sure if it would cause a problem on a v6. certainly wouldnt stop it starting
