if you see in this diagram for a 2004 gmc envoy 6 cyl. there is no compression on valve item #12 in the following link. is this the fuel rail valve that i need to check psi from? i checked the valve that is by the fuel filter for the fuel pump and there is enough compression there. so question is, is item #12 the fuel rail valve i need to be checking?

items checked
coils- good ohms reading there
replaced coil boots
replaced spark plugs
cleaned out throtle body
before i check the fuel injectors i would like to know if item 12 is the fuel rail valve. please advice, thank you! all the information found in your website is awesome!
