3.4L V6 (distributorless) I have a bad #4 fuel injector (PO304). The problem is finding the #4 fuel injector. There are numbers stamped on manifold, but their location on the air intake + next to a cylinder raises questions on which cylinder is which. I have extracted the fuel rail and attached injectors, I need to know which one is #4. Is number 4 located on the front(facing radiator),or the back(facing the firewall)?

How do you know what side is the front? My engine sits with 3 injectors paralell to the radiator, and 3 injectors parallel to the windsheild. It faces differently then your diagram.
