Answers :

The injector should be spraying. It is possible that it is clogged. You can dissassemble and reassemble and clean screan with any carb cleaner. If the regulator is bad fuel will go back to the tank instead of going to the injector. It is possible that the pump in the malibu can send fuel but not hold pressure under load. I would check the fuel pressure on a gage and see if in spec. If okay than suspect clogged screan
