True, CIS systems are always spraying fuel when they are running, but it takes 40-50 psi of pressure to make them open and spray. It should only let fuel through if the pressure is above its opening pressure. A leaking injector will let the fuel go through intil the pressure gets to 0 psi. So yes they can leak and put too much fuel in the cylender.
